It could be duplicate of JDK-8227647. It has similar error message: WB error: failed to blocking compile at level 4 method EqvUncastStepOverBarrier::test WB error: blocking compilation is still in queue!

I think the only explanation is that the compilation just failed (Graal threw an exception). It's hard to say why, since I cannot reproduce the failure anywhere. I thought we could have bailed out because of a JVMCI task timeout (see CompileBroker::wait_for_jvmci_completion()) but that would take 10 seconds. The test through seems to have failed immediately. I'm deferring this to 15 to see if it magically starts reproducing.

Possibly a race but I can't see how. It works fine on my machine. Compiles that are initiated from a JVMCI thread are non-blocking so there shouldn't be any effect on the blocking compiles from user threads.
