PI12744: Connection timeout property of SOAP client ineffective in some cases

Fixes are available

APAR status

Closed as program error.

Error description

The JVM property
com.ibm.websphere.management.soapSocketConnectionTimeout
does not work if a remote host drops offline after a
connection was previously established.  The connection timeout
will revert to the default of the underlying hardware platform.

A thread dump will show a hung thread as follows:
void
java/net/PlainSocketImpl.socketConnect(java.net.InetAddress,
int, int)  (Native Method)
void
java/net/PlainSocketImpl.doConnect(java.net.InetAddress, int,
int)  source: PlainSocketImpl.java:370
void
.........

org/apache/soap/util/net/SSLUtils.buildSSLSocket(String, int,
String, int, String, String, String)  source: SSLUtils.java:259
........
com/ibm/ws/management/connector/soap/SOAPConnectorClient$4.run()
source: SOAPConnectorClient.java:373

* RECOMMENDATION:                                              *
****************************************************************
Connections to remote hosts were tested with a timeout
on the initial attempt, but this result was then cached and
reused without a timeout in subsequent attempts.  If a remote
host dropped offline after the initial connection, a
subsequent connection attempt to that host could change to the
operating system default value, which might be too long.

Problem conclusion

The code is corrected to use the timeout from the JVM property
consistently for both initial and subsequent connection
attempts.

APAR PI12744 is currently targeted for inclusion in Fix Packs
7.0.0.33, 8.0.0.9, and 8.5.5.3 of WebSphere Application Server.
