2006-07-28 Gary Benson <gbenson@redhat.com> * prims.cc (_Jv_CreateJavaVM): Move setting runtimeInitialized from the start to the end of the function. Remove references to VMThrowable.trace_enabled. * java/lang/natVMThrowable.cc (fillInStackTrace): Use runtimeInitialized rather than trace_enabled to decide whether to inhibit stack trace generation. * java/lang/VMThrowable.java (trace_enabled): Removed.
