[rules-users] java.lang.ArrayIndexOutOfBoundsException thrown in mvel2's compiler when running drools5.3 final.

[Miles Wen]

hi all,
the exception below is usually thrown when the system is busy(usually 9-10
am everyday);
The rules runs perfectly when unit test or any other time when the system
is not very busy(like 22:00 - 4:00 every day);
Our system processes 13000000 pieces of data each day, with
4-5 java.lang.ArrayIndexOutOfBoundsException thrown on average.It's not
very often but doubtful.
The logs are shown below:

I looks like there's some issue in mvel2's parser.The problem occurs when
dynamic compiling mvel2 code.
And every ArrayIndexOutOfBoundsException is thrown around here:
 'Helper.containsAny(offerSubject, ((Set)colMap.get("_set_212")))' .This is
a custom static function call which implements come sort of operation not
supported by drools5.
Is this a bug about mvel2?Or any one encountered this problem also? How
could I avoid it?
Thnaks!
