Subject [jira] Commented: (FELIX-527) Improve Error Reporting during binding
Date Fri, 04 Apr 2008 20:15:25 GMT

    [ https://issues.apache.org/jira/browse/FELIX-527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12585740#action_12585740

Patrick Forhan commented on FELIX-527:
--------------------------------------

That's why I cross-posted this... I think Felix SCR may be able to do something better here,
too, in addition to not having pax blow up.  In our particular case, an AbstractMethodError
is thrown (with detail message).  It comes to SCR as an InvocationTargetException, with a
cause/target exception of the AME.  I think then Felix SCR is looking at the getMessage()
of the ITE, which may not have been set.

With any exception (and especially InvocationTargetExceptions), the root causes tend to be
more important and informative.  Can Felix dig a little deeper here?
