The problem is related to how SWT extracts libraries when they are missing. If multiple processes are started quickly when libraries are missing, the following happens: 1) Process A notices that library is missing and starts extracting it 2) Process B finds incomplete library and loads it 3) JVM crashes with SIGBUS - BUS_ADRERR in NativeLibrary.load() I'll prepare a patch for this: use a temp file and rename it when fully extracted.
