While compiling the JDK with GCC 8.1, I discovered an invalid bit test in test/hotspot/jtreg/serviceability/jvmti/StartPhase/AllowedFunctions/libAllowedFunctions.c.
(status & JVMTI_CLASS_STATUS_INITIALIZED) == 1 Which only has a chance of being true if JVMTI_CLASS_STATUS_INITIALIZED has a value 1 (its actual value is 4, but that's beside the point). My proposed fix is to test for != 0 instead. I chose this instead of testing for equality to JVMTI_CLASS_STATUS_INITIALIZED purely for cosmetic reasons.
