As seen in the runtime version check and debug log: The Mapping of GL4ES3 using these drivers tries to use GL3.hw instead of GLES3.hw! GL4ES3 GLProfile[GL4ES3/GL3.hw] Your test code is incomplete, TextRendering is missing! It would be better to demonstrate a wrong context/profile logic with a most small test code. Further more, it would be great if you (and everybody) could just offer the test code via git, so I can pull it :) However, I will try to analyze the wrong mapping .. Official unit test to test profile/context mappings: com.jogamp.opengl.test.junit.jogl.acore.TestGLProfile01NEWT 79ac86efa3f0b114ce456e7f2a8ef341932fd17c Test enhancements triggering issue 'Bug 1052 - OpenGL ES 3.0 Mesa 10.1.3 Caught GLException: Not a GL4ES3 implementation' - TestGLProfile01NEWT: Complete GLProfile and GL-object and GLContext validation - On OpenGL ES 3.0 Mesa 10.1.4 it produces: test06GLProfileGL4ES3(com.jogamp.opengl.test.junit.jogl.acore.TestGLProfile01NEWT) javax.media.opengl.GLException: GL4ES3 is neither GL4bc, GL4 nor GLES3 at com.jogamp.opengl.test.junit.jogl.acore.TestGLProfile01NEWT.validateGLProfileGL4ES3(TestGLProfile01NEWT.java:531) at com.jogamp.opengl.test.junit.jogl.acore.TestGLProfile01NEWT.validateOffline(TestGLProfile01NEWT.java:708) at com.jogamp.opengl.test.junit.jogl.acore.TestGLProfile01NEWT.test06GLProfileGL4ES3(TestGLProfile01NEWT.java:948) i.e. wrong mapping of request GL4ES3 -> GL3 278a884e459b1180a947ff24edecdef1a7fc6cb7
- TestGLProfile01NEWT: Allow ctx.isGLES3Compatible() and hence GL4ES3 on GL3bc and GL3
- GLProfile: Remove GL4ES3 mapping using GL3bc and GL3, only GL4bc, GL4 and GLES3 are allowed in static mapping.

@Xerxes: Thx for finding this one.
