            Jenkins Windows Service Not Starting
            Asked 2021-Feb-17 at 15:58

            Jenkins was up and running for months without issue, as a windows service.

            I did some Jenkins updates (copied a newer/later .war file to the .jenkins folder) and some windows updates also occurred. The version that I have is Jenkins 2.263.3.

            I did a lot of trolling through the documentation and other StackOverflow tickets and found out that the JENKINS_HOME environmental variable was missing. I added this.

            Here is what my investigation reveals.

            1. The Java environment variable is set - see below:

            Answered 2021-Feb-17 at 15:58

            The service is starting and stopping without issue.

            The problem I suspect was that the original install of Jenkins was very old, and I presume that it may have been a 32-bit application at the time. The current updates seem to 64-bit apps. Since the original install, Jenkins was updated - with changes spanning several major releases from the original install (.war file updates). The jenkins.exe file - that starts the service was never updated.

            The error message 'System.BadImageFormatException' after much research indicated that the issue was related to compatibility difference between 32/64 bit executable. I presume it was expecting a 64-bit executable but was getting a 32-bit exe.

            To solve this problem I installed the latest version of Jenkins on my local PC.

            On the Server I backed up the files:

            • jenkins.exe
            • jenkins.exe.config

            I then stopped Jenkins on the Server, where the Service was not Starting (from the terminal window with Ctrl+D).

            I then replaced these 2 files on the server with the latest files from my local installation.

            Service started the first time.

            Our 64 bit C program instantiates a JVM using JNI. Currently we are using Adopt Open JDK 8.0.1920.12 and everything works fine. Now we are trying to migrate to Adopt Open JDK 11.0.8.0. When using that one, JNI_CreateJavaVM always returns -1.

            What I did is basically a) download the JDK (file OpenJDK11U-jre_x64_windows_hotspot_11.0.8_10.zip) b) put its content into the folder that previously contained the Java 8 JDK. This folder can be found in the PATH environment variable

It has all elements and attributes named in lowercase, but actually some of them should be mixed case (as can be seen by the error message that it doesn't find attribute className).

            The linker (ld) cant find these libraries. I had a similar issue with just lpcre2-8 on Ubuntu. I fixed my issue by installing:

            sudo apt-get libpcre2-dev

            I imagine the second error with bz2 will be fixed with:

            Java consumes memory more than Xmx argument
            Asked 2019-Jul-07 at 20:12

            I have a very simple web server class (based on Java SE's HttpServer class).

            When I start the compiled class using this command to put limits on memory usage:

            java -Xmx5m -Xss5m -Xrs -Xint -Xbatch Test

            Now if I check memory using top command, it indicates ~31MB of resident memory is used by the Java process which executes my class.

            I was wondering what is that 30MB used for?

            Java runs on a virtual machine, rather than directly on your hardware. This means that this machine needs its own memory to run. The 5MB you allowed your program likely means that there is another 26MB being used by the Java Virtual Machine (JVM).

            ANSWER

            Answered 2017-Jun-02 at 14:36

            It seems that XmlReader stops validation of element on first encountered error. Here is a link to description of old (obsolete) XmlValidatingReader ValidationEventHandler:

            If an element reports a validation error, the rest of the content model for that element is not validated, however, its children are validated. The reader only reports the first error for a given element.

            And it seems it is the same with regular XmlReader (though its documentation does not mention it explicitly).

            In first examples errors are either in innermost elements (such as invalid text value of element) or at the last child element, so they are all reported and nothing skipped. However in last example you introduce error at the beginning of root Abc001 element, so the rest of Abc001 content is skipped, together with all errors.

            C# Service not moving files to correct folder
            Asked 2018-May-21 at 21:08

            I have configured a windows service using an xml config file. The service is supposed to determine which folder a csv file goes to depending on the number of fields in the file. The number of fields also determines which version of the software generated the file, whether Version 3 or Version 4. Version 3 csv files should go to its own folder and the same for version 4 before they are collated. Currently both versions are mixed up and because of this, the collation process gets corrupted and multiple files are not being processed by the windows service. Below is a sample of the code snippets. When I run the windows service and check the event viewer, I keep getting the error in the catch statement - "Error checking csv file" and It moves the files to the exception folder instead of to the correct folders. Any insight would be greatly appreciated.
