---------------------------------------
Summary: Threads hanging in dispose() on SSLHandshakeException
Key: DIRMINA-1077
URL: https://issues.apache.org/jira/browse/DIRMINA-1077
Project: MINA
Issue Type: Bug
Environment: JDK 1.8.0_162-b12
Xubuntu 16.04.
Ubuntu Linux, Kernel 4.4.0-112-generic
Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz
Reporter: Christoph John
Attachments: SslTestHandshakeException.java, emptykeystore.sslTest,
mina-dispose-hang-2.0.17-SNAPSHOT.txt,
mina-dispose-hang-with-DIRMINA-1076-patch.txt
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/}}.
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 additonally 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

In both stack traces the process is hanging in a call to dipose() although one
time it is in the NioSocketConnector and in the other case in the
NioSocketAcceptor.
