Local fix Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server developers      *
*                 utilizing the JSPBatchCompiler at deploy     *
*                 time.                                        *
****************************************************************
* PROBLEM DESCRIPTION: JSPBatchCompiler compilation takes      *
*                      hours to complete war files that        *
*                      contain a large number of JSPs.         *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Customers are advised to batch compile JSPs at deploy time.
If a Web Application Archive contains a large number of JSPs,
the compilation process creates a large number of
javac compiler objects (one per jsp) for compiling thus
degrading performance.
Problem conclusion
Modified the JSPBatchCompiler to create only one compiler
per directory in a WAR file.  This improved performance
without changing the underlying batch compilation process.
The new process will first parse the directory of JSPs
and then compile the list of parsed JSPs.
