Java Question [SOLVED] "--add-opens ... =ALL-UNNAMED" arg not working on Linux Deployment

[cjpryor]

I have completed the development of a custom Library for my own internal usage. Thanks @Erel !!!

It works great in all modes on all platforms including the deployed packages EXCEPT when it is deployed to Linux. In that case I am stuck on the following error even though I added the necessary argument to the release_java_modules.txt file of my B4JPackager11 Project.

More details:

My java code:

Only issues I encounter are on Linux ... as follows:

When running on Linux Using B4J Bridge
- with #PackagerProperty: VMArgs = --add-opens b4j/net.sf.jasperreports.engine.fill=ALL-UNNAMED in B4J Main
- Reports work running in Debug, Release, and Release (obfuscated) Modes with following warning
- (java:2474): Gdk-WARNING **: 16:50:09.054: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.
- which is logged after return from call to ReportWrapperLibrary
- similar issue found here: https://stackoverflow.com/questions/55446534/how-to-fix-java22494-gdk-warning

When running release on Linux
- Built from standalone package built in B4J
- Using B4JPackager11 project from within B4J pointing to jar on Linux

I saw a post where adding --add-opens b4j/net.sf.jasperreports.engine.fill=ALL-UNNAMED to another persons release_java_modules.txt file solved the "module b4j does not export net.sf.jasperreports.engine.fill to unnamed module @0x5219dd7f" error for them but it does not seem to be working for me.

Thanks in advance for any help!

When running on Linux Using B4J Bridge

- Reports work running in Debug, Release, and Release (obfuscated) Modes with following warning

#PackagerProperty only has effect when you build a standalone package using the internal packager.

You should run the external packager using B4J-Bridge and you should set the VMArgs global variable. It can also be done with the generated json file.

Thank you for your response! It helps a bunch! I did (attempt to) use the external package manager using B4J-bridge as mentioned in my original post (as quoted below), but it looks like I did not configure it correctly.

When running release on Linux
- Built from standalone package built in B4J
- Using B4JPackager11 project from within B4J pointing to jar on Linux

That project is where I found the release_java_modules.txt that I modified. However, I did not make any changes to the parameters in the project file itself. These are my current configuration which I see now are incomplete.

Sub Process_Globals
    
    'Linux
    Private InputJar As String = "/home/nmcollector/data/CP_deploy/Linux/NMCollectorCP.jar"
    
    Private NetFrameworkCSC As String = "%WINDIR%\Microsoft.NET\Framework64\v4.0.30319\csc.exe" 'windows only
    Private IconFile As String

    ExcludedModules = Array("javafx.web") 'comment this line if using WebView
    Private IncludedModules As List' = Array("jdk.crypto.ec")
    Private AdditionalModuleInfoString As String '= "exports net.sf.jasperreports.engine.fill;"
    Private VMArgs As String
    'non configurable variables:

    Private Windows As Boolean

Thanks again!

yup, the deployment works now! Thanks again @Erel
