JNI Exception from calling getColumnFamilyMetaData twice about rocksdb

[neilramaswamy]

Update: I have bisected the issue to #11770. I've looked through the PR and don't see anything obviously wrong that could be the root cause. (One thing I noticed was that this line does an exception check on the env, even though in that case we should check if it's a nullptr. But that's not the issue, since locally, that doesn't fix the error.)

Hello @neilramaswamy,

I think you really found bug and you are right with the PR which cause this bug. It looks like JNI code for SstFileMetaData wasn't updated during this PR. Let me fix it.

Hi @rhubner, were you planning on opening a PR? If not, I can investigate whether the fix you proposed actually works (I haven't actually checked), and I can create one.

Hello @neilramaswamy,

I just submitted PR #12474 which should fix this issue. It will be great if you can test it and let me know the results.
