It looks quite clear that two threads are trying to create a groovy.lang.Closure and the parallel execution of groovy.lang.MetaClassImpl.addProperties method can lead to a deadlock between synchronization on BEANINFO_CACHE object in java.beans.Introspector and synchronized java.beans.PropertyDescriptor.getReadMethod method.
