RegTest-test com/sun/jdi/GetLocalVariables4Test.sh test fails intermittently.
The cause of the problem is that there is a dangerous code in ShellScaffold.sh that
can lead to race conditions:

        if [ -r $jdbOutFile ] ; then
            # Something here causes jdb to complain about Unrecognized cmd on x86.
            tail -$nlines $jdbOutFile | $grep -s "$1" > $devnull 2>&1
            if [ $? = 0 ] ; then
                break
            fi
        fi
        tail -2 $jdbOutFile | $grep -s "The application exited" > $devnull 2>&1
        if [ $? = 0 ] ; then
            dofail "Waited for jdb msg $1, but it never appeared"
        fi

The expected output can appear after
tail -$nlines $jdbOutFile | $grep -s "$1" > $devnull 2>&1
and before
tail -2 $jdbOutFile | $grep -s "The application exited" > $devnull 2>&1

Actually it seems to happen quite often on my Windows ME machine.

After I had changed the code as follows:

        if [ -r $jdbOutFile ] ; then
            # Something here causes jdb to complain about Unrecognized cmd on x86.
            tail -$nlines $jdbOutFile | $grep -s "$1" > $devnull 2>&1
            if [ $? = 0 ] ; then
                break
            fi
        fi
        tail -2 $jdbOutFile | $grep -s "The application exited" > $devnull 2>&1
        if [ $? = 0 ] ; then

            if [ -r $jdbOutFile ] ; then
                tail -$nlines $jdbOutFile | $grep -s "$1" > $devnull 2>&1
                if [ $? = 0 ] ; then
                    break
                fi
            fi

            dofail "Waited for jdb msg $1, but it never appeared"
        fi

the test passed 5 times of 5.

Please note that the test also fails due to bug 4786183 on Windows ME.
