The appletviewer still alive even through the shell
was interrupted. The shell can be interrupted as result
of the bug 6329251 (fixed in b61). This leads to all the
following regression tests will fail during deleting
of the file ('err', created by the appletviewer).

In spite of the fact that the bug 6329251 was fixed
the regression test logic should be revised.
It would be a good idea to kill the appletviewer
manually immediately.
