How to configure location of vfs nestedjar

Issue

• I have to run two jboss application servers on a Linux container. I want to configure the location of the nestedjar-files for both jboss application server so that they are different are different. Instead of /var/tmp for both jboss server I want to have /var/tmp/jboss1 and /var/tmp/jboss2 for the nestedjar-files. How can I configue that?
• Regarding nestedjarNNNN.tmp files appearing in /tmp directory, is it possible to configure JBoss to make it to create them in a specific location?
• I have noticed a huge memory consumption in our Jboss instances which is related to a known Virtual File System (VFS) native memory leak . Having opted to use the JVM option -Djboss.vfs.forceVfsJar=true , JBoss is storing the “nestedjar*.tmp files in the /tmp server path. I would like to know if it is possible to change the path the files are stored?
