[rules-users] Strange rule compilation issue.

[Edson Tirelli]

   Ok, this one was hidden for a long time. Interesting no one stumbled on
it before you.

https://jira.jboss.org/jira/browse/JBRULES-2424

   The problem is triggered in case your fact class/interface has a method
that matches the following 3 conditions:

* it is public
* its name starts with "set"
* it has no parameters

    Your fact interface had a method:

public XXX setup();

    That would make the ClassFieldInspector class to raise an exception,
making it impossible to create any field accessors for it.

    Anyway, it is fixed now on trunk (to be released in M2) and branch
5.0.x. Meanwhile, the possible workaround is to break one of the three
conditions above: either make the method non-public, or rename it to not
start with "set" or add at least one (dummy) parameter to it.

    Thanks for reporting.

     Edson
