Here's something (perhaps) to be concerned about: A recently-reported
regression in Sun's proprietary 6u14 (and hence also in hsx14) causes
debugging breakpoints to be ignored in some circumstances.  The bug is
reproducible with both the client and server VMs, but only using the
serial GC.

The primary Sun bugid is 6862295 [1]; see also the downstream bug first
reported in Eclipse [2].  Dan Daugherty is working on a fix, which we'll
publish when available, but in the meantime hsx14 has this bug.

Is the existence of this bug in hsx14 a reason to delay replacing the
current jdk6/hotspot repo with Andrew's newer version?  Let me know.
