HTTP *ADMIN server won't start

My pair of newly acquired V5R2 LPARS both run HTTP servers. (These were built from SAVE 21 images after being spun off from another company).

One partition starts HTTP *ADMIN with no problem. The other fails with:

HTP8703 Diagnostic 40 10/10/11 12:04:53.216472 QZSRAPR QHTTPSVR *STMT QZTCJK QHTTP

Message . . . . : An attempt to initialize a Java Virtual Machine failed.
Cause . . . . . : In the properties file specified by the JkWorkersFile
directive, a worker was configured with the type "jni". This configuration
requires that the worker process URL requests in a Java Virtual Machine in
the HTTP server job. The attempt to initialize the Java Virtual Machine has
failed. The HTTP server did not start. Recovery . . . : Look for other
messages in the job log that may provide more information. It is possible
that the classpath that is configured in the properties file is not correct.
Configure the JkLogFile directive to specify a file where detailed tracing
information can be stored. Configure the JkLogLevel directive specifying a
value of "debug" to enable detailed tracing information. Start the HTTP
server again and examine the output. If you can not determine the cause of
the error, contact your service provider for assistance.

Both servers are at the same PTF level for both 5722JV1 and 5722DG1.

I have added the -vv option on the start command to get verbose output.

One of the logs points to this file being the problem, yet the file is the same on each LPAR:

0000005D:473312 mod_jk: Error while processing the workers properties file /QIBM/ProdData/HTTPA/admin/conf/workers.propertie [s]
0000005D:473336 mod_jk: jk_error_exit()
0000005D:473344 ap_log_error()

0000005D:473456 log_error_core(): "[Wed Oct 12 12:04:57 2011] [emerg] Error while opening the workers"

I am at a loss on what else to look at. Any ideas would be greatly appreciated.
