Thank you for your investigation.

Looks like something that we cannot fix, but we may mention it in
RELEASE-NOTES, or on the FAQ page on the Wiki site (editable by everyone). It
is a regression in JDK and concerns not only Tomcat, but any java application
that runs with its own value of java.io.tmpdir.

> 1) Tomcat specifies -Djava.io.tmpdir=$CATALINA_BASE/temp in its JVM options.

Note, that if you are using catalina.(sh|bat) to start Tomcat, then the path to
the temporary directory can be customized by setting the "CATALINA_TMPDIR"
environment variable.

One can set it either before running the scripts, or in a bin/setenv.(bat|sh)
file.

> 2) Java 6 Update 23 places the hsperfdata_$USER directory in this directory
