Cool.

If you can avoid singletons, p2 will allow installation of multiple 
version of the same plugin. And you shouldn't see this error.
Otherwise, it means that you'll need either to uninstall previous 
version of the bundle, or run tests on a clean application everytime.

Singletons are only necessary when plugin define extension points or 
extensions. Bundle org.jboss.tools.foundation.test doesn't provide 
anything like that. Just get rid of the plugin.xml, remove the singleton 
directive in 
https://github.com/jbosstools/jbosstools-base/blob/master/foundation/tests/org.jboss.tools.foundation.core.test/META-INF/MANIFEST.MF#L4 
, and p2 would allow several installations of the bundle so you'll be 
able to sequentially run tests on the same application without 
uninstalling anything.
