of other true* libraries I've looked at, constitute some of the most<br>
complicated and overengineered pieces of code I've ever seen :-)<br>
<br>
I have not looked at truezip sources and don't know what kind of class<br>
lookup it uses, there was a similar problem reported in 396554 [1],<br>
which appears to be a general problem when using TCCL with<br>
Equinox/ContextFinder and Class.forName. There are couple of articles<br>
linked from the bugzilla that explain the problem in more details,<br>
probably [2] the most detailed and relevant.<br>
<br>
In any case, I am not aware of any thread context classloader "leaks" in<br>
m2e, so if somebody believes there is such leak please provide a quality<br>
fix and I'll review and apply it.<br>

Hey all:<br>
<br>
A user found a strange bug while using astools and publishing a zipped<br>
project. The bug is basically that truezip ( a library we use) can't<br>
initialize because it can't find a class. It can't find the class<br>
because the thread's classloader is from plexus classrealms, and not the<br>
standard eclipse classloader that we'd expect.<br>
<br>
So basically, either forge or m2e is changing a worker's classloader,<br>
and not putting it back. This (if true) could be a critical issue, since<br>
that thread / worker will probably never have the proper classloader<br>
again for the workspace session.<br>
<br>
I encourage anyone with access to m2e or forge to look into this and<br>
verify their respective codebases are behaving properly with regards to<br>
classloaders. Feel free to look at the jira and ask any for more details<br>
or any questions you might have that might help in tracking this down.<br>
