Hi Kelly,

I'm using a local (BNE) mirror of east coast /java/devtools, but I 
checked east and west and both have the same unpatched version of CC.

I'm running on a partially patched (maybe to u3?) S10u1:

SunOS nebula-bne 5.10 Generic_125100-10 sun4u sparc SUNW,Sun-Fire-V210

I can try on another machine.
