[jboss-jira] [JBoss JIRA] (DROOLS-388) Inconsistent behavior of "contains" operator

[Davide Sottara (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-388?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Davide Sottara updated DROOLS-388:
----------------------------------

    Description: 
The compiler accepts constraints such as

{code}
Person( fullName contains 'Jr' )  // should be fullName.contains('Jr')
{code}

Interestingly, MVEL evaluates it as the string operation "contains", but 
once the constraint is jitted it is again evaluated as a collection operator.

That is, a rule such as:
{code}
  when
    $s : String( this contains "foo" ) 
  then
{code}
with inputs "foo1" .. "fooN" effectively fires an unpredictable number of times before starting to fail silently
