How reproducible:


Steps to Reproduce:
1. Build a rule with the following LHS: 
$p : Person( name == null || (name in (\"Alice\", \"Charlie\", \"David\"))==false )
2. Try to compile the package


Actual results:
Build fails with RuntimeException

Expected results:
Build is successful

Additional info:
Changing the constraint to the following works as well:
$p : Person( name == null || (name not in (\"Alice\", \"Charlie\", \"David\")) )
