Nandor Kracser commented on CURATOR-41:
---------------------------------------
Throwable#getSuppressed() is already in [JDK
7|http://docs.oracle.com/javase/7/docs/api/java/lang/Throwable.html#getSuppressed()].
> Curator masks/loses exception in LockInternals

>
> private boolean internalLockLoop(long startMillis, Long millisToWait,
> String ourPath) throws Exception
> try {
> ...
> }
> catch ( Exception e )
> {
> doDelete = true;
> throw e;
> }
> finally
> {
> if ( doDelete )
> {
> deleteOurPath(ourPath);
> }
> }
> Say ... throws an exception. catch sets doDelete = true. Then deleteOurPath
> throws an exception. We never find out what the original exception was that
> caused the mutex to fail.
> In JDK8, I think we get the extra Throwable#getSuppressed() call, which will
> return us this extra exception, but we aren't on JDK8 yet.
