no felix-3.2 osgi framework with jdk8
some classloaders produce uri to embedded jars within jars (like jruby-stdlib.jar) which
the underlying URLClassloader can not handle. currently some of those protocols like 'jar'
will be handled by JRubyClassLoader with reimplementing the class loading itself.

this approach instead copies the embedded jar to temp file and passes the file-uri the
underlying URLClassLoader. this also allows to bypass all the scanning and indexing of all
other URLs added to the JRubyClassLoader.
