Bug 79321 Compiler preference page: disabling default compliance settings should leave 'disallow' combos disabled
I200411230838 and before: - Preferences > Java > Compiler: set compiler compliance level to 5.0 and check 'Use default compliance settings'. - Uncheck it again => the two 'Disallow identifiers...' combos become enabled - they should stay disabled with setting 'Error'. - Set source compatibility to 1.4 and back to 5.0 => 'Disallow ...' are OK now.
