QUESTION
Suppose I have configured a continuous flight record for my JVM using the following flags
...ANSWER
Answered 2021-May-29 at 07:27Unfortunately, the link you have ranks high in search engines, but it is six years old. You can find the latest documentation here (JDK 16), which is very much the same as JDK 11.
It's not possible to dump part of a memory-based recording. In your example, you have to remove 'disk=false' and -XX:FlightRecorderOptions, and add 'maxsize=200M' to -XX:StartFlightRecording:
QUESTION
This is a follow-up question of Lean pass type as parameter
I tried jmc's suggestion, which seemed to work, but then I got stuck at another point. The original purpose of the question was to define the categories of groups and rings, but now apparently I am unable to define group morphisms:
...ANSWER
Answered 2021-Apr-16 at 12:01You are redefining the + notation which will very quickly lead to headaches. Have a polymorphic + notation is very helpful. (How will you denote the addition in a ring?)
Further points:
- you should use
structureinstead ofclass - mathematically, you are defining monoids and monoid homs, not groups and group homs
This works though
QUESTION
The previous version of JDK Mission Control 5.5.2 bundled with Oracle JDK 7 had the possibility to add a WebLogic plug-in, which allows viewing the SQL queries, servlets between other components as seen in this image.
Then the new JDK Mission Control 7.1.2+b04 doesn't seem to have a similar plug-in or at least it's more complicated to apply it.
When trying to investigate, the JMC is pointing to https://download.oracle.com/technology/products/missioncontrol/updatesites/oracle/7.1.2/ide/update-site-instructions/index.html stating that the plugin must be installed via Eclipse 4.8 or later, so the latest Eclipse is 2012-12 was installed, and then the plugin with https://download.oracle.com/technology/products/missioncontrol/updatesites/oracle/7.1.2/ide/ as well, as seen in this image:
The Eclipse IDE was restarted and now it got a new icon in the menu bar:
which connects (or at least it tries to connect) with the Java processes running in this local station:
but that's not the WebLogic plug-in I expected, similar to the one available in the previous version of JMC.
Does it exist a WebLogic plug-in in JMC7.1.2 similar to the existing in JMC5.5.2?
...ANSWER
Answered 2021-Mar-03 at 04:29To install WebLogic plug-in for JMC, go to Help menu and select Install New Software menu item. Expand "Mission Control (Oracle)" and then "Flight Recorder" and you will find "WebLogic Pages" plug-in. Follow the instructions on screen to complete installation of plug-in.
This is described in the Oracle JMC 7 User Guide under Install JMC Standalone Application in the "Install Plug-ins for JMC Standalone Application" sub-section.
QUESTION
I was following Kevlin Henney's Youtube video on Lambdas in programming. At about 20:30 - 20:40 in his video he gives this code snippet:
...ANSWER
Answered 2021-Jan-26 at 05:16It appears that MSVC has an issue with handling the deduction of ternary statements when in the presence of the /permissive- flag. The /permissive- flag should be forcing MSVC to compile with strict standards conformance, however ironically this appears to be breaking what should be valid code.
This can be reproduced on Compiler Explorer easily: Live Example. This appears to be fixed in newer MSVC versions with v19.25 onward Live Example
Unfortunately there are few ways to fix this since it's a compiler bug. You're limited to:
- Updating your compiler,
- Removing
/permissive-, or - Not using ternary statements that return different types (e.g. use
if/elsewith different returns instead)

QUESTION
When profiling my application, I can see boxing of Double values done in the Array[Double] constructor, like this (copied from JMC / JFR):
ANSWER
Answered 2020-Oct-22 at 15:34It seems the optimization is quite fragile. Changing the types and literals involved causes the optimization to be done (or not).
var el = Array[Double](1)
var el = Array[Double](1.0)
Both produce the ugly code:

Does anyone know what the * following a filename in macOS terminal means?
All the file names in the folder:
/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands
have a * trailing them and I'm not sure why.
For example:
...ANSWER
Answered 2020-Sep-28 at 01:30As for the executable-looking emulator that you can't actually execute, this can happen when the dynamic loader requested by emulator doesn't exist. You can check what kind of file emulator is with the command file emulator, and check what dynamic loader and libraries it needs with ldd emulator (any line showing “not found” is something you need to install). Given the name of the directory and the size of the file, emulator is probably a Linux x86 binary. I suspect you have an amd64 system. If so, you need to install a runtime environment for 32-bit applications; on Ubuntu, you need the ia32-libs package (and perhaps also ia32-libs-gtk). You could also get this error message for a script whose interpreter as indicated in the #! line doesn't exist.
same question here.
QUESTION
Are JMC binaries included in open JDK ? We have openjdk-1.8.0.252 in our Linux platform , but we do not have JMC ?
Can we install JMC as separate application that runs on JVM already installed ? Can we use JMC in production environments ? If yes, please let me know the path to install JMC for open JDK
...ANSWER
Answered 2020-Sep-16 at 15:42Java Mission Control was previously a proprietary commercial offering from Oracle. Oracle then open-sourced it as a subproject on the OpenJDK project.
See that subproject page, Mission Control, and this wiki page. Notice the “Java” trademarked word has been dropped from the name.
As of 2020-06, the current version of the Mission Control project is 7.1.1. A version 8 is available for preview.
Ditto for Oracle’s Flight Recorder product, now open-sourced within the OpenJDK project. See JEP 328: Flight Recorder. Flight Recorder is currently being bundled with the JDK in my expertience, while Mission Control is a separate download.
Java 11In Java 11, the current LTS version, you will need to download and install the binary of Mission Control.
You can download a binary installer from various vendors.
The vendors I know of include:
- Azul Systems — Zulu® Mission Control
- Adoptium (formerly AdoptOpenJDK) — JDK Mission Control 7.1.1 (& 8.0.0 preview)
- Oracle – JMC 7.0.1
Mission Control requires a JDK to run. Here is a flowchart I made to guide you in choosing a vendor for a JDK implementation.
Java 8Be aware that Oracle changed its licensing on its product Oracle JDK. That product now requires a fee for use in production. As I recall, even before that change, Oracle required a fee for use of its Java Mission Control product in production.
Now Oracle has generously transferred the product to the OpenJDK project. Since open-sourcing under the OpenJDK project, other vendors are free to back-port Mission Control to Java 8 per the new licensing terms.
I know of at least one such vendor:
- Azul Systems
- See their product Zulu® Mission Control. This product is included with both their free-of-cost Zulu Community product and their commercial Zulu Enterprise product.
QUESTION
I am trying to write a console app for our elementary school which will read courses, students, coursework (etc) from Google Classrooms and write it to our SQL Server database. This is the first time I have ever used an API and I have very little experience with C# - but school starts in two days, so I'm using Google searches to figure out how to do it.
I pasted my code below that successfully reads the courses from Google Classroom and writes them to our SQL Server. I thought I could use the same logic for the rest of the tables (students, Coursework, etc). However, when I tried to add students, there is a problem with this line (list is underlined in red):
...ANSWER
Answered 2020-Aug-30 at 22:31Looking further at the signature, Students.List requires a course ID as a parameter, which is currently not provided. On top of this, the return type for Students.List is CoursesResource.StudentsResource.ListRequest. To fix, replace the line with:
