Missing setContextClassLoader

[jackybourgeois]

Hello,

Doing some tests with MOEA framework inside a Kevoree component, I came accross the exception below from the code of an Input port:

java.lang.IllegalArgumentException: interface org.moeaframework.util.progress.ProgressListener is not visible from class loader

Thanks to François I understood the ClassLoader was the wrong one. It was the one from the component who fired the message (on Output port) instead of the one from the receiver (on Input port).

We set manually the ClassLoader to work around in the Input port method:

Thread.currentThread().setContextClassLoader(MyComponentWhoReceive.class.getClassLoader());

Thx Jacky for the report, as planned together this fix will be include in the next rolling release beginning of next week.
