Synchronizing pattern compilation block in PatternMatchNode
-----------------------------------------------------------

         Key: CAY-567
         URL: http://issues.apache.org/cayenne/browse/CAY-567
     Project: Cayenne
        Type: Bug

  Components: Cayenne Core Library
    Versions: 1.2
    Reporter: Andrus Adamchik
Assigned to: Andrus Adamchik
    Priority: Minor
     Fix For: 1.2

Cayenne "like" expression (a subclass of PatternMatchNode) causes an NPE in multi-threaded situtations. The method that causes it is "PatternMatchNode.getPattern(..)". While we do not make any special guarantees as to the thread-safety of the expressions, this case looks like the one we need to fix. Especially since the fix is trivial.
