Michael McCandless resolved LUCENE-2688.
----------------------------------------

    Resolution: Fixed

This issue was fixed, as a side effect of fixing LUCENE-2689, which removed the acquireTestLock
method (the only thing using j.l.management.*) entirely.

>    Looks like FSDirectory defaults to NativeFSLockFactory, and this class refers to java.lang.management
package to generate a unique lock. java.lang.management is not available in Android 2.2 and
hence a runtime exception is raised. The workaround is to use another custom LockFactory or
SimpleFSLockFactory, but Fixing NativeFSLockFactroy will help.
> Thanks,
