[jboss-jira] [JBoss JIRA] (DROOLS-740) NoSuchMethodError at runtime while evaluating String and Long

------------------------------------------
Toshiya>
Out of curiosity, why did you remove 20-times-loop from the test case? Is there any trick
to force JIT compilation immediately?
Mario>
The trick I use to test and fix JIT compilation issues is setting this flag to true:
https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/jav...
This forces immediate JITting of constraints. When I fix a jit-related bug (and from time
to time) I then ran the whole test suite with that flag set to true to check that jit
compilation is working with all known use cases.

Key: DROOLS-740
URL: https://issues.jboss.org/browse/DROOLS-740
Project: Drools
Issue Type: Bug
Components: core engine
Affects Versions: 6.2.0.Final
Reporter: Toshiya Kobayashi
Assignee: Mario Fusco
Fix For: 6.3.0.Beta1
When you write a LHS like this,
{noformat}
Person( name == "Elizabeth" + new Long(2L) )
{noformat}
you will face NoSuchMethodError after 20 times evaluation.
