Andrew Purtell commented on HBASE-10527:
----------------------------------------
bq, The Oracle JDK implementation of BAOS zero initializes the underlying
byte[]. However, IBM JDK does not seem to. This seems to matter in computing
the SHA1 for the token identifier password, where the trailing \x00 bytes do
not change the SHA1 in the Oracle JDK, but the additional uninitialized junk
does change the resulting SHA1 with IBM JDK.
That makes complete sense. All that digging for such a simple fix. Thanks so
much Gary, +1
