Description Jan Koehnlein

Even though it's discouraged, Java member names can contain dots and dollars.
The ClasspathTypeProvider can deal with that situation. But JDT-based ones can't as the resource URIs are derived form the JDT signature, which is a plain String. 
So it is impossible to distinguish a class 'Outer$Inner' from an inner class 'Inner' inside the top level class 'Outer'.

This is especially annoying, as Google Guice prefixes copied classes from Guava with a $.

See org.eclipse.xtext.common.types.access.impl.ClasspathTypeProviderTest.testFindTypeByName_$ImmutableList()
