The following exception might be thrown from from
CacheDeployUtils while removing the webservices cache
directory.

The callstack below is seen in the SystemErr.log file.

[8/11/09 15:49:16:659 EDT] 000000bf SystemErr     R
java.lang.NullPointerException
[8/11/09 15:49:16:659 EDT] 000000bf SystemErr     R  at

DeployUtils.java:51)
....

This intermittent error is most likely to occur when multiple
threads are causing the webservices cache to be removed at the
same time.

Problem conclusion

The problem occurs due to a timing issue involving 2 threads
simultaneously trying to delete the same cache directory
structure in the file system. The code was structured such
that it called File.listFiles() twice and implicitly expected
the same result.  The code is corrected to make a single call
to File.listFiles() to avoid the timing issue.

APAR PK94048 fixes this same problem for the WebSphere
Application Server V6.1 Feature Pack for Web Services.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.9.  Please refer to the Recommended Updates
