Yes, JDK 1.1.7 (v3 and v1a) for Linux has also this
problem.  But, JDK 1.2 pre-release 2 and JDK 1.1.6 from
IBM can handle that situation well.  And TYA and shuJIT
can also deal with the special division even with
Blackdown JDK 1.1.7.

The problem was reported by Matt Welsh on the Java-linux
list several months ago.

I'm looking for release of your OpenJIT.
