java regexp inline modifier in dsl causes java.lang.IndexOutOfBoundsException
-----------------------------------------------------------------------------

                 Key: JBRULES-2399
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2399
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler
    Affects Versions: 5.0.1.FINAL
         Environment: Windows XP, Eclipse 3.4 with Drools 5.0.1 plugin
            Reporter: Lev Kochubeevsky
            Assignee: Mark Proctor


Does Drools 5 support java regexp inline modifiers? I tested my pattern matching in java and it works fine:
System.out.println (
        Pattern.matches("(?i)update the message",
                        "uPdAte the message")); // true

I'm trying to use the same thing in DSL:
[then](?i)update the message fact=update ( m );

DSLR:
update the message fact

and get:
