[perf] Maven classloading performance improvements: https://jira.codehaus.org/browse/PLX-467

[Martin Kočí]

Hi,

I read the whole interesting discussion about maven parallel classloading.
In addition to parallel classloading would be nice to fix this one:
https://jira.codehaus.org/browse/PLX-467 in PlexusClassworld. We have
builds with JAXB/WSDL and the getStackTrace invocations take because of
heavy classloading according to YourKitProfiler 15% of the build time.

Thanks

Martin
