8179527: Ineffective use of volatile hurts performance of Charset.atBugLevel()

Yes, this line should be removed. Currently there are two @run directives which cause running the testcase twice. Once in normal mode and once with bugLevel set to 1.4. So, if "sun.nio.cs.bugLevel" ought to be removed then the second iteration of the test is obsolete. And then one should probably remove the whole "compat" handling in the test.

Best regards
Christoph
