[jira] Commented: (MPJALOPY-9) Jalopy Classes not found

["Lukas Theussl (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MPJALOPY-9?page=comments#action_61414 ] 

Lukas Theussl commented on MPJALOPY-9:
--------------------------------------

I am not sure this is the right fix for this problem: how can the root classloader fix a ClassCastException? I checked that going back to the configuration of the 1.3.1 release of the jalopy plugin, everything works for me without having to specify the root class loader. I have no idea though where the CCE above is coming from. I'd suspect a configuration problem, since, as Wendy points out herself, it still works for other people. On the other hand, the jalopy plugin 1.4 seems completely borked, see my comment at MPJALOPY-10.

> Twice now, on two different machines (same codebase, though,) the
> Jalopy plugin was working fine and then suddenly stopped working with
> the error below.
> Full output of maven jalopy -X is here:

> The only thing that changed was Jalopy's config file.  Reverting those
> changes to a known good state didn't help.  Other developers on the

> Does anyone see anything that looks suspicious?
