Just adding a comment so people who see hotspot java probes not working against
running java processes might find this bug report. The hotspot main thread does
nothing except wait for all other threads to exit. Which can trigger this bug.
This happens for example on a 2.6.32-220.23.1.el6.x86_64 kernel.
