QUESTION
The class JsonSerializerOptions has the following property:
ANSWER
Answered 2022-Mar-24 at 23:55What exactly is happening in that last example? I might be having a mental lapse, but I don't think I've encountered such syntax before. Can someone point out where it is documented?
It's the collection initializer syntax. It's documented here. And more directly with regards to read-only props here.
Some classes may have collection properties where the property is read-only...You will not be able to use collection initializer syntax discussed so far since the property cannot be assigned a new list. However, new entries can be added nonetheless using the initialization syntax by omitting the list creation.
This syntax works for 'collection types that implement IEnumerable and has Add with the appropriate signature as an instance method or an extension method.'
For deeper reading, take a look at the spec where it says more precisely:
The collection object to which a collection initializer is applied shall be of a type that implements
System.Collections.IEnumerableor a compile-time error occurs. For each specified element in order, normal member lookup is applied to find a member namedAdd. If the result of the member lookup is not a method group, a compile-time error occurs. Otherwise, overload resolution is applied with the expression list of the element initializer as the argument list, and the collection initializer invokes the resulting method. Thus, the collection object shall contain an applicable instance or extension method with the nameAddfor each element initializer.
QUESTION
Using JMeter v5.4.3 and Jmeter plugins manager CMD (v1.7):
We're getting the following error while running jmeter plugins manager on a JMX and the required plugins are not getting installed, but surprisingly the same JMX is running fine on JMeter. Anything we're missing here?
...ANSWER
Answered 2022-Mar-24 at 10:35Why "surprisingly"? Your .jmx script file contains a null character which is not allowed character in XML.
JMeter ignores this in order to allow maximum flexibility and JMeter Plugins Manager doesn't.
Plugins Manager is a separate project which is not related to JMeter upstream by any means.
Moreover it's a message of WARN severity so you can just ignore it (or if it causes problems in automated log analysis you can configure JMeter logging to not display this warning by adding the next line to log4j2.xml file)

QUESTION
Environment:
Linux + JDK 11 + Gradle 5.0
I have several gradle projects which must build from sources without Internet connection/ For example this one git clone --depth 1 --branch 3.0.0 https://github.com/bobbylight/RSyntaxTextArea.git for that first of all I built this project online then copy ~/.gradle to $PROJECT_DIR/grdl , next I want to test this build offine. I perform gradle --stop , clear whole ~/.gradle directory then turn off Internet and run following script:
ANSWER
Answered 2021-Sep-13 at 14:01I think you are hitting this issue: https://github.com/gradle/gradle/issues/1338
That is, cache items are non relocatable. Copying the whole ~/.gradle folder may not be enough, especially if ~ resolves to a different path than in the original machine (i.e. different user). The full path needs to be exactly the same (with Gradle 5.0).
The issue suggests however that version 6.1 makes the cache relocatable, so perhaps you'll have more luck with a recent version (7.2 is the latest at this point in time).
EDIT: The release notes and these docs confirm that the cache can be copied across deployments as of version 6.1.1.

ANSWER
Answered 2021-Aug-10 at 22:02(Just clutching at straws here…)
One thing occurs to me: your main() method is an instance method, which I've not seen and may be a problem.
In stand-alone programs, main() cannot be an instance method, as there's no instance to call it on yet. I don't know whether the Spring loader makes special allowance for that situation, but in case it doesn't I'd suggest trying to move it either into a companion object:

I know we have similar questions already answered here. but for some reason none of the options are working for me.
Below is the error i'm getting:
...ANSWER
Answered 2021-Jun-01 at 19:10Spark provides Jackson itself, and not the version you expect. The error is likely caused by having 2 conflicting Jackson versions in the classpath.
You have 2 options:
- force a specific Jackson version with some properties (see Classpath resolution between spark uber jar and spark-submit --jars when similar classes exist in both for instance)
- update your build definition to use the same Jackson version as provided by Spark
Spark 2.3.0 comes with Jackson 2.6.7.1 (can be checked here for instance: https://mvnrepository.com/artifact/org.apache.spark/spark-core_2.11/2.3.0).
QUESTION
I am writing an Angular front end for an API that occasionally serves Infinity and -Infinity (as bare words) in the JSON response object. This is of course not compliant with the spec, but is handled a few different JSON libraries, albeit optionally. I have an Angular service in place that can successfully retrieve and handle any retrieved entity that does not have these non-conforming values. Additionally, I have managed to get an HttpInterceptor in place which just logs when events trickle through, just to be sure I have it connected properly.
The issue that I am facing is that the HttpInterceptor seems to allow me to do one of two things:
- Catch/mutate the request before it is sent to the API, or
- Catch/mutate the request after it comes back from the API, and also after it is parsed.
What I would like to do is very similar to this question for native javascript, but I have not been able to determine if it is possible to tie into the replacer function of JSON.parse in the Angular Observable pipe (I think that if tying into that is possible it would solve my issue).
I have also found this question for Angular which is close, but they appear to have been able to handle changing the response to something other than the bare-words, which I don't have the liberty of doing.
This is the current implementation of my HttpInterceptor, note that it does not actually make any changes to the body. When retrieving an entity without these bare-word values, it logs to the console and all is well. When retrieving an entity with any of these bare-word values, an error is thrown before the HERE line is hit.
ANSWER
Answered 2021-Mar-14 at 20:36I was able to figure out how to achieve this, and it came down to:
- Modifying the request to return as text instead of json
- Catch the text response and replace the bare word symbols with specific string flags
- Parse the text into an object using
JSON.parse, providing areviverfunction to replace the specific string flags with the javascript version of+/-InfinityandNaN
Here's the Angular HttpInterceptor I came up with:

Install json-lib
You can use json-lib like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the json-lib component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
