Description
Two threads calling GroovyShell.parse from the same GroovyShell instance enter in deadlock (see the stack below).
I'm not sure whether this multi-threaded use is supposed to be supported or not, so feel free to reject it in case GroovyShell is supposed to be used only from one thread or from multiple threads but with explicit synchronization.
Anyway this seems similar to GROOVY-4050
