    After uninstallation or undeployment, the file descriptors associated to the classpath of the uninstalled artifacts are not closed, and the JARs of a dedicated classloader not closed too.
    So after several installation/deployment and uninstallation/undeployment, no more file descriptor is available and an error occurs.
    All open resource must be closed (like file) and static instance must be unreferenced.

Because the uninstallation/undeployement is not complete, the classloader is not unloaded, so resources are not freed.

It's not only a problem into the kernel, but bad Java code in component can cause the problem.
So, we must improve uninstallation/undeployment in the kernel, but also improve our component testing process adding tests about repeated installation/unsinstallation and checking memory consumption

Isn't that solved by the switch to Java 7 and the use of close on the classloaders? See PETALSDISTRIB-109.
