Problem conclusion
-
The SSL Channel was modified so that the closing handshake write no longer blocks the thread and provides a timer to control how long the channel will attempt to complete the write. A new system property was added to enable the timer for all SSL channels that are created. The property is "timeoutValueInSSLClosingHandshake" and accepts an integer value to configure the amount to wait (in seconds) before giving up on completing the write. The default value for this property is -1, which means the channel will wait indefinitely for the write to complete. It can be set as JVM custom property on the following panel: Application Servers > {Server Name} > Process definition > Java Virtual Machine > Custom properties
