Work Description: the-thing commented on PR #84:
URL: https://github.com/apache/mina/pull/84#issuecomment-6359010667
I think this PR is stable now and I will mark it for review as soon as the
sluggish ubuntu will pick up the job.
Additional deadlock flow graphs attached to JIRA.
**Notes**
- The bug existed for G0 handler before our patch in 2.2.10
- The fix for large SSL messages exposed the bug in G1 handler as well in
2.2.10 patch
> Do you consider this fix serious enough that it requires a release? Seems
so to me...
Possibly, but as mentioned for G0 handler + PROXY combination is an existing
bug. We detected this in QuickFIXj end-to-end proxy test suite (we had only G1
handler covered).

> While updating MINA 2.2.10 in QuickFIXj we encountered a deadlock in
> end-to-end SOCKS proxy tests.
> It looks like this was introduced by DIRMINA-1199 fix however all
> combinations of tests fail with a deadlock, which also means that there is an
> existing problem with {{org.apache.mina.filter.ssl.SSLHandlerG0}}
> implementation in versions before 2.2.10.
> Currently I was only able to confirm SSL + SOCKS proxy combination failures,
> but some of the failures in mentioned QuickFIXj PRs look suspicious. It will
> be easier to investigate if we solve this problem first.
