An unexpected exception, such as a
com.ibm.crypto.hdwrCCA.provider.JCECCARuntimeException, was
thrown under the ZAioTCPReadRequestContextImpl.readCompleted,
ZAioTCPWriteRequestContextImpl.writeCompleted, or the
ZIOPChannelBridge.sendMessage invocations.  The processing of
this unexpected exception resulted in abandoning the
connection without proper cleanup.  The other-side of the
connection experienced a non-responsive connection.
The following examples illustrate the failures seen:

Problem conclusion

Code has been modified in the
ZAioTCPReadRequestContextImpl.readCompleted,
ZAioTCPWriteRequestContextImpl.writeCompleted, and the
ZIOPChannelBridge.sendMessage routines to properly handle
unexpected exceptions.   This should result in the connection
closing.

APAR PI16990 is currently targeted for inclusion in Fix Packs
8.0.0.10 and 8.5.5.3 of WebSphere Application Server.
