This case now fails:

STEP: Create jaxrs problem with Application problem (Multiple application definition - one class extending Application and one application servlet definition in web.xml)
STEP: comment servlet definition in web.xml
ASSERT: problem marker in web.xml disappears
ASSERT: problem marker in application class disappears
FAIL: problem marker in application class doesn't disappear, because problem markers are not linked now -> project has to be built to correctly remove both problem markers
