OK, thanks. The code path with the exception message comes from SurfaceData.c function GetSDOps: static SurfaceDataOps * GetSDOps(JNIEnv *env, jobject sData, jboolean callSetup) { SurfaceDataOps *ops; if (JNU_IsNull(env, sData)) { JNU_ThrowNullPointerException(env, "surfaceData"); return NULL; } ops = (SurfaceDataOps *)JNU_GetLongFieldAsPtr(env, sData, pDataID); if (ops == NULL) { if (!(*env)->ExceptionOccurred(env) && !(*env)->IsInstanceOf(env, sData, pNullSurfaceDataClass)) { if (!(*env)->GetBooleanField(env, sData, validID)) { SurfaceData_ThrowInvalidPipeException(env, "invalid data"); } else { JNU_ThrowNullPointerException(env, "native ops missing"); } } } else if (callSetup) { SurfaceData_InvokeSetup(env, ops); } return ops; } I need to get such a system to be able to reproduce this first. It's not readily available to me. Unfortunately, I'll be away for a while. I'll look at this again when I'm back.

I cannot reproduce this so far on Fedora 27. SwingSet2.jar works fine for me. Same for FileChooserDemo.jar. What linux system is this?

Actually I see it with an exploded build too .. Also since the exception is in finding xrender ops I tried -Dsun.java2d.xrender=false but that doesn't help. There's no exception printed (I guess it is caught somewhere) But the window is completely blank.
