JDK            : JDK1.5.0-b47 (also fails with jdk1.4.2-fcs)
Testbase       : Regression-test

The test tries to run a program using Runtime.exec(). The program has 
the following permissions:

-r-xr--r--    1 ka94536  green       15992 Apr 16  2004 motif-child

The problem is Runtime.exec() cannot run a program with such permissions 
on AMD64 platform.
It needs at least ug+x.

Runtime.exec(new String[]{"/bin/sh", "-c", ...})

I have been able to reproduce the problem.

If you have a Solaris user with uid>64k,
and if the home directory is NFS-mounted on Linux-AMD64,
then accesses to the NFS-mounted drive from Linux will
see truncations of the uid.  Linux-amd64 is a system
with 32-bit uids, but evidently there are still remnants
of 16-bit uid code in the system that may take another
Linux kernel cycle to fully resolve.

The implementation checks the uid of the executable file
in statExecutable.  This is a design error.  Hopefully
both this bug and

4052517: (process) Solaris Runtime.exec won't execute programs belonging to other groups

can be fixed by trying to execute the program without trying
to predict its success ahead of time.

I finally fixed the long-suffering

4052517: (process) Solaris Runtime.exec won't execute programs belonging to other groups

and this bug (5033302) was also magically fixed, as predicted by the previous
evaluator.
