[ http://jira.jboss.com/jira/browse/JBSEAM-1756?page=all ]
Pete Muir closed JBSEAM-1756.
-----------------------------
Resolution: Done
Ok, I resolved it by calling setAccessible(true) if the type is not public, but the method was found when doing getMethods() (getMethods() only returns public members). AFAICS this is safe.
No reply from Jacob.

> I'm trying to get the number of results from the following query (in components.xml):
