Christoph John updated DIRMINA-1077: ------------------------------------ Description: 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 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 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 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. was: This is probably related to DIRMINA-1076.
