	jcifs-0.7.0b4+ requires Java 1.2 not 1.4.

	Use jcifs-0.6.7. That does not exibit the problem you're seeing. Nor does jcifs-0.7.0b6 from my limited testing. The 0.6 series is what you should be using in production anyway. It should work
just as well for what you're doing.

	Otherwise I don't know off-hand what exactly is causing the problem.
