Starvation occures sometimes on SerialSession#close()
------------------------------------------------------
Key: DIRMINA-813
URL: https://issues.apache.org/jira/browse/DIRMINA-813
Project: MINA
Issue Type: Bug
Components: Transport
Affects Versions: 2.0.0
Environment: OS: Win32 XP-Pro
rxtx Version :2.1.7.4_v20071016
Reporter: Christian Schwarz
It seems that an Starvation occures sometimes when we call close() on a
SerialSession, the Methode never returns.
We observed our Application with JConsole, it shows that no Deadlocks are
detectable, so we assume that we have a starvation here.
