The test can fail due to sun.reflect.GeneratedConstructorAccessor1 not being found. Here is the error message: java.lang.Exception: Failed dcmd queue, Class for name: 1310 ! sun.reflect.GeneratedConstructorAccessor1::newInstance (53 bytes) at CompilerQueueTest.validateMethodLine(CompilerQueueTest.java:101) at CompilerQueueTest.main(CompilerQueueTest.java:76) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.sun.javatest.regtest.MainWrapper$MainThread.run(MainWrapper.java:94) at java.lang.Thread.run(Thread.java:745) JavaTest Message: Test threw exception: java.lang.Exception: Failed dcmd queue, Class for name: 1310 ! sun.reflect.GeneratedConstructorAccessor1::newInstance (53 bytes) The failure is nondeterministic because it depends on whether the method sun.reflect.GeneratedConstructorAccessor1::newInstance was already compiled or not. The failure can be reproduced deterministically (at least on my machine) by running the test with -XX:CompileThreshold=1 or with -XX:CompileThresholdScaling=0.01 so that methods are compiled earlier than usual.
