===================================================================
Author: Ralph Sennhaser <sera@g.o>

The idea is to apply the pax markings before using a freshly built jdk. Be it
for running tests or building additonal vms or after bootstrap to build the
final jdk.

There are currently two types of pax markings with the userspace utilities
chpax and paxctl. Both types of pax marking are base on modifing the ELFs. A
third type based on xattrs is in development.
