[SRU justification]

[Impact]

I'd like, not only to trace the java process, but use the new support
for openjdk tracing in systemtap, both the hotspot tracing and the
method tracing.

Accordingly i installed the ddebs.ubuntu.com[1] repository to install
the kernel debuging symbols - i can then call a stap script that uses
kernel tapsets but not yet java ones. I did notice a package called
openjdk-7-jdk-dbgsym and tried to install it to see if this had the
systemtap tapsets for the openjdk, but this conflicts with the
openjdk-7-dbg package (which then ubuntu doesn't let me bug report since
the openjdk-7-jdk-dbgsym package is not from the 'official' servers).
And if i uninstall that one and install the other it doesn't help
anyway.

If the steps i followed to try to get systemtap java method tracing in
ubuntu were incorrect and this can be done with packages from your
reporsitories, feel free to close.
