Download Description
PQ99045 resolves the following problem:

ERROR DESCRIPTION:
After installing the CacheMonitor and DynaCacheESI applications on the server, Cache Monitor shows "Internal Server Error".

In the SystemOut.log, it includes:

[10/28/04 19:06:23:882 PDT] 4f97362 OSEListenerDi E PLGN0021E: Servlet
Request Processor Exception: Virtual Host/WebGroup Not Found:
The web group /_DynaCacheEsi/esiInvalidator has not been defined


PROBLEM SUMMARY:

USERS AFFECTED:
All WebSphere® Application Server users

PROBLEM DESCRIPTION:
Application Server implements java.io.InputStream.read(byte[ ] b, int off, int len) method. When len is 0, Application Server does not return 0 immediately.

RECOMMENDATION:
Application Server implements java.io.InputStream.read(byte[ ] b, intoff, int len) method.

Java™ SDK 1.4 and Java SDK1.3 require when len is 0, this method should return 0. Application Server's implementation fails to do that.

This may cause some performance issues.

PROBLEM CONCLUSION:
Application Server implements java.io.InputStream.read(byte[ ] b, int off, int len)method. When len is 0, it will now return 0 immediately.

The fix for this APAR is currently targeted for inclusion in fix pack 5.1.1.4.
