Description

I've found a deadlock in MemoryAwareConcurrentReadMap.get that affects calls to MetaClassRegistryImpl.getMetaClass. This particular case seems to happen very infrequently; the last time I saw it happen was after my program had been running for 4.5 hours. I have seen it more than once, however, so I'm fairly certain this bug will strike any Groovy program that runs long enough.

This issue may be related GROOVY-1890 but I can't be certain from the information I have.
