EVALUATION The problem is that the code in PredictedDynamicCallGenerator::generate assumes that the generation of the slow path always succeeds. This might not be the case when we hit the node limit while generating the slow path.
09-11-2011
SUGGESTED FIX Removing the assert and returning on failed slow path generations results in: @ 3 org.jruby.runtime.invokedynamic.InvocationLinker::testMetaclass (17 bytes) NodeCountInliningCutoff @ 16 java.lang.invoke.MethodHandle::invokeExact (10 bytes) inline (hot) @ 35 java.lang.invoke.MethodHandle::invokeExact (56 bytes) inline (hot) @ 35 java.lang.invoke.MethodHandle::invokeExact (11 bytes) inline (hot) @ 7 org.jruby.runtime.invokedynamic.InvocationLinker::invocationFallback (104 bytes) method handle not reached 4 COMPILE SKIPPED: out of nodes parsing method (not retryable) and the test finishes successful.
