===================================================================
I got this while running the JCKs through javatest on linux/x86 on several
tests... I believe one of them was
  api/java_awt/JobAttribute/index.html#ctor2

The nightly tests on rt_baseline for 7/9/03 also found this on solaris/x86,
test (in vm_quicklook) jit/common/misctests/Pi.
