App Development Troubleshooting And Hints

Java Fx Headless Tests Fail with GLXBadContext

Running Java Fx application tests in headless mode using monocle fails on Linux using the following error: libGL error: failed to create drawable, X Error of failed request: GLXBadContext Major opcode of failed request: 152 (GLX).

Did not happen on asl7 cluster environment, most likely because there is no graphic acceleration involved using remote desktop.

Use LIBGL_ALWAYS_SOFTWARE=1 mvn test to make sure the software renderer is used.
