Question

java.lang.IllegalAccessException when running/building on Ubuntu 20.04

Manodiestra opened this issue 3 years ago · comments

OS: Ubuntu 20.04
java: openjdk 16.0.1 2021-04-20
ant: 1.10.7

I get an error:

java.lang.IllegalAccessException: class javax.media.j3d.JoglPipeline cannot access class sun.awt.X11GraphicsDevice

I cloned the repo and tried building as specified in the README.md:

ant create_run_jar copy_res
cd out/production
java -Djava.ext.dirs= -jar jmavsim_run.jar

I also tried building the distribution package

ant distro

Then unzipped it and ran it from the command line with java -jar jmavsim_run.jar

In both cases it stops with error output as follows:
(Full output)

Options parsed, starting Sim.

Any help to resolve the issue would be appreciated.

The issue was the use of OpenJDK. The project requires a proprietary JDK to build.

You may also keep your existing JDK 16 and use JVM option --illegal-access=permit

can someone help me ı am getting same error but ı couldnt understand the answers, detailed answer could be useful. I have both jdk(17.02) and open-jdk(17.01)

@alper50
In your terminal run java --version and see what it spits out. If it's pulling OpenJDK, then either uninstall it or switch the default Java JDK in your shell PATH to point to the proprietary JDK.

Or you can try doing what @jzy3d suggested and run java --illegal-access=permit -jar my.jar instead of java -jar my.jar.

@Manodiestra
java --version output is = openjdk 17.0.1 2021-10-19
OpenJDK Runtime Environment (build 17.0.1+12)
OpenJDK 64-Bit Server VM (build 17.0.1+12, mixed mode)

and ı decided to run java --illegal-access=permit -jar my.jar but the output is = ' Error: Unable to access jarfile my.jar '
