Description
SnappyDecompressor.c has the following code in a few places:
THROW(env, "Ljava/lang/InternalError", "Could not decompress data. Buffer length is too small.");
this is incorrect, though, since the THROW macro doesn't need the "L" before the class name. This results in a ClassNotFoundException for Ljava.lang.InternalError being thrown, instead of the intended exception.

Examination of related files shows Todd's comment is manifestly correct. Attached is a patch for branch-1.0. Please review.
Regarding "InternalError" being a questionable choice of Throwable to throw: I guess the implementor wanted Error rather than Exception, and there aren't that many choices of Error.
In branch-1.0, the ZlibCompressor/Decompressor do not have the incorrect "Ljava" with THROW usage.
+1, patch looks good to me. Please upload a trunk patch as well.
Uploaded patch for trunk. Should also work in 0.23 and 2.0. As Todd noted, includes fix for lz4 too.

Leaving Jira open pending code review and commit of fix for trunk and branch-2.
+1, trunk patch looks good to me. In the future, we should follow the declared policy of committing to trunk before branch-1.
Rebased patch to trunk. Fixed one more instance of L that the earlier patch had missed or the trunk had gotten since. Will commit once jenkins +1's.

This is not merged into branch-2 and is still an issue there.
Agree. We also meet the same issue in 2.x releases like discussions in HADOOP-12033. I will reopen this JIRA and merge the trunk patch back to branch-2.
Commit patch to branch-2.
Pulled this into 2.6.1 after Akira Ajisaka verified that the patch applies cleanly. Ran compilation before the push.
Just pulled this into branch-2.7 (release 2.7.2) as it already exists in 2.6.1.
branch-2 patch applies cleanly. Ran compilation before the push.
This bug seems to occur in lz4 as well.
It also seems like the wrong kind of exception to throw - InternalError is for JVM-internal unexpected conditions.
