Hi,
Hmm, this sounds like the commons.classloader should be a compile dependency of
the jspc plugin such that on runtime the commons.classloader is visible to the
plugin.
You might try to add the commons.classloader as a dependency to the plugin
declaration and see whether it works. If so, you might create an issue asking
for the commons.classloader dependency to be explicitly added to the jspc
plugin.
Regards
Felix
