PK74176: COMPILED CLASS FILES FOR JSPS ARE STORED IN SERVANT SPECIFIC TEMP DIRECTORIES INSTEAD OF COMMON SERVANT TEMP DIRECTORY.

Error description

When JavaServer Pages (JSP) are compiled at runtime, the
classes created are
placed in the servant specific temp directory (these are
sub directories in the config HFS temp directory which contain
the name of the servant plus the UUID).  The servant specific
temp directories are cleaned up when the server or servant is
recycled, which means the JSPs will need to be recompiled again
after a crash or normal recycle.  These classes should be placed
in the common server temp directory instead, which will persist
through a recycle, and eliminate the need to recompile the
JSPs.

Local fix

Precompiling the JSPs will place the classes in a different
location, thus eliminating this problem all together.

****************************************************************
When JSPs are compiled at runtime, the same generated classes
are placed in each servant temporary directory.  Those classes
are then deleted when the server or servant is recycled.  This
is inefficient because it requires disk space to hold each
copy of the same compiled classes.  If the servant or server
crash, these classes will not be cleaned up automatically.  In
addition, the deleted JSP classes have to be recompiled after
each servant restarts.

Problem conclusion

The JSP container was modified to generate the compiled
classes into a common server temporary directory which will
also persist after the server or servant has restarted.
