Subject [jira] [Commented] (DIRMINA-1077) Threads hanging in dispose() on SSLHandshakeException
Date Mon, 19 Feb 2018 16:54:00 GMT

    [ https://issues.apache.org/jira/browse/DIRMINA-1077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16369313#comment-16369313

Jonathan Valliere commented on DIRMINA-1077:
--------------------------------------------

I'm waiting to commit DIRMINA-1076 until I can resolve this issue.  I want to make sure this
isn't an unintended consequence of the patch for DIRMINA-1076.  Thank you for your patience.

>         Environment: JDK 1.8.0_162-b12
> Xubuntu 16.04.  Kernel 4.4.0-112-generic

> This is probably related to DIRMINA-1076.
> See attached unit test {{SslTestHandshakeException}}. For the test to run you also need
the attached file {{emptykeystore.sslTest}} placed into {{mina-core/src/test/resources/org/apache/mina/filter/ssl/}}.
The purpose of the test is simply to provoke an {{SSLHandshakeException}}. I have seen the
problematic behaviour once in a while on processes implemented with QuickFIX/J but now luckily
got it reproduced in a unit test.
> When I run it against MINA-2.0.17-SNAPSHOT I will get (almost instantly) the stack trace
as in {{mina-dispose-hang-2.0.17-SNAPSHOT.txt}} and the test will hang.
> When ran against MINA-2.0.17-SNAPSHOT plus the patch from DIRMINA-1076 I will get the
stack trace from attached file {{mina-dispose-hang-with-DIRMINA-1076-patch.txt}} and additionally
the following log output (but the test will still hang):
> {noformat}
> XXX javax.net.ssl.SSLHandshakeException: SSL handshake failed.
> Exception in thread "pool-337-thread-1" java.lang.AssertionError: Internal Session Count
is Negative
> 	at org.apache.mina.core.polling.AbstractPollingIoProcessor$Processor.run(AbstractPollingIoProcessor.java:674)
> 	at org.apache.mina.util.NamePreservingRunnable.run(NamePreservingRunnable.java:64)
> 	at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)
> 	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
> 	at java.lang.Thread.run(Thread.java:748)
> {noformat}
> In both attached stack traces the process is hanging in a call to dispose() although
one time it is in the NioSocketConnector and in the other case in the NioSocketAcceptor.
