This website doesn't seem accessible.

We also have a testsuite for testing the probes with systemtap for

http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2010-March/008629.html

I couldn't find the provider_probes_checker.pl script in the sources.
Are they available? Maybe we can somehow combine the tests.

Yes, they seem useful indeed.
Were they discussed on the list before? I only noticed them now.
