[rules-users] compound LHS error, getting "Parser error. Contact Dev Team"

[Eric Miles]

I have a compound LHS statement that is causing the parser to fail.
Here is my exact stacktrace:

org.drools.compiler.DroolsParserException: Unknown error while parsing.
This is a bug. Please contact the Development team.

This is the statement that is causing me problems:

not(UserRole((role == Role.TIMEKEEPER, delegateFor == $supId) || (role
== Role.SUPERVISOR, delegateFor == $tkpId)) from $actorRoles)

Remote out one of the conditions from the ||, it compiles fine.  Such
as:

not(UserRole(role == Role.SUPERVISOR, delegateFor == $supId) from
$actorRoles)


or

not(UserRole(role == Role.TIMEKEEPER, delegateFor == $tkpId) from
$actorRoles)

Is my syntax incorrect or is there a bug?

Thanks!
