[rules-users] Drools hangs on parsing a Query

[spotlight2001]

I read this in some oracle forum:



"You may want to check if your updating the HashMap concurrently. If you are
then the HashMap can get internally corrupt (The items in one bucket can get
a circular linked reference) and result in a infinite loop upon calling
get(). If this is the case use ConcurrentHashMap instead."

[https://forums.oracle.com/forums/thread.jspa?threadID=2326247]



I wonder if changing org.drools.util.CompositeClassLoader$CachingLoader

from HashMap to ConcurrentHashMap solves this.

actually "long pSpmaId" shouldnt be resolved. Since drools should know its
type "long" anyway from parameter declaration.
