This is a consequence of fixing bug 31799. Since no per project info is incorrectly cached any longer, then this issue is now detected. Must fix to preserve special opening rules for working copies outside the classpath.
Added catch block in JavaElement.getElementInfo() to handle projects that don't have the Java nature and added regression test WorkingCopyNotInClasspathTests.testSimpleProject()
Verified.
