Downloadable files


Abstract

ClassNotFoundException exception is thrown when the server classpath does not have the value class when using the COPY_TO_BYTES CopyMode.

Download Description

PM11665 resolves the following problem:

ERROR DESCRIPTION:
ClassNotFoundException exception is thrown when the server classpath does not have the value class when using the COPY_TO_BYTES CopyMode. There are cases where the eXtreme Scale runtime does not need to inflate the value to its Object form, but the runtime was still inflating the values.

LOCAL FIX:

PROBLEM SUMMARY

USERS AFFECTED:
All users of WebSphere eXtreme Scale Version 7.0 who are using the COPY_TO_BYTES CopyMode.

PROBLEM DESCRIPTION:
ClassNotFoundException exception is thrown when the server classpath does not have the value class when using the COPY_TO_BYTES CopyMode.

RECOMMENDATION:
None

The WebSphere eXtreme Scale runtime was changed to no longer convert the value of a map entry from a byte array to its Object form when that Object form is not needed. This change allows users who are using the COPY_TO_BYTES CopyMode to not require their value classes on the server classpath when they are not using OptimisticCallbacks, MapIndexPlugins, Loaders, queries, or any other plug-in that requires the value to be inflated.

PROBLEM CONCLUSION:
An interim fix will be made available for this APAR. A future cumulative fix will correct the problem for WebSphere eXtreme Scale Version 7.0.
