Environment

Symantec SiteMinder Agent SDK R12.8 Any

 

Cause

Customer modified the sample JavaTestClient program from Broadcom to test in their environment. When used as JNI, it worked without issue. When testing as Pure Java, connection errors were seen.

Resolution

The exception is actually from Java and not Symantec SiteMinder code.

From : https://docs.oracle.com/javase/7/docs/api/java/nio/channels/UnresolvedAddressException.html

“Unchecked exception thrown when an attempt is made to invoke a network operation upon an unresolved socket address. “

The exception occurs at sun.nio.ch.Net.checkAddress, as detailed above, when the address being used to connect to is unresolvable. In this case the Policy Server address. It could be an invalid IP address, an unresolvable hostname or a typo in the address.

When the customer reviewed the address they were using, it was found that there was a trailing space after the IP address that does not get trimmed, leading to the Java exception.

Removing the trailing space resolved the issue.
