Jim observed the following assertion failure in service_hs_baseline
nightly testing results on 2003.08.25:

# Internal Error (/net/balvenie.sfbay/export/imgr_home/ws/
20030821131759.dcubed.service_hs_merge/src/share/vm/runtime/
deoptimization.cpp, 481), pid=18405, tid=4
#

# Error: assert(fr.can_be_deoptimized(),"checking frame type")

I checked my most recent Tiger NSK results (Tiger-B15 snapshot VM
dropped into a Tiger-B14 JDK) and I found this assertion occured
in 28 distinct NSK tests:

12 of these bugs are already on the nsk.knownbugs list for another
bug/failure so on 16 of these are actual regressions.
