Nope. It is still broken. You should not modify the BeanMetaData inside the Kernel. This is a representation of what the user wants. What you have done is added a reference to the class in the SuppliesMetaData which once the bean gets uninstalled will cause a memory leak. UninstalledBeanMetaData (waiting to get reinstalled) -> SuppliesMetaData -> Class -> ClassLoader (that is supposed to be garbage collected). I don't even see why you are doing this? All you need to do is to modify the kernel registry plugin entry point getEntry() to use your contextsByClass. http://docs.jboss.org/nightly/microkernel/docs/reference/en/html/registry... Did you try running the full testsuite? org.jboss.test.KernelAllTestSuite. or from the command line ./build.sh -f build-test.xml tests There are currently 38 failures and 1 error.
