BTW, this is 2D code. I'm cc'ing 2d-dev@ and bcc'ing awt-dev@.

Hi all, I'm cross-posting this to lambda and awt lists. Although it happens in AWT code, the crash might or might not have anything to do with AWT. See below... When trying to start NetBeans 7.3beta using OpenJDK built from head of lambda forest using either old or new build system, the JVM crashes in native code always in the same function: # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f84da3ba913, pid=9489, tid=140208720062208 # # JRE version: OpenJDK Runtime Environment (8.0) # Java VM: OpenJDK 64-Bit Server VM (25.0-b02 mixed mode linux-amd64 compressed oops) # Problematic frame: # C [libmlib_image.so+0x94913] mlib_ImageSet+0x13 # ... ...

I'm compiling and running on Linux Fedora 17, amd64. I would like to try a build from jdk8 forest that is as close as possible to the head of lambda forest. Which revision should I choose? Regards, Peter P.S. I checked the code (just source files containing native functions in above stack trace and BufferedImage.java) and they don't differ between jdk8 and lambda heads. But it might be that jdk8 has other differences to lambda that make it execute different AWT code in this situation...
