The MotifDnDAcceptanceTest test fails with the next output:

java.lang.RuntimeException: Incorrect drop data: null
        at MotifDnDAcceptanceTest.start(MotifDnDAcceptanceTest.java:184)
        at com.sun.javatest.regtest.AppletWrapper$AppletThread.run(AppletWrapper.java:131)
        at java.lang.Thread.run(Thread.java:619)
STATUS:Failed.Applet thread threw exception: java.lang.RuntimeException: Incorrect drop data: null
result: Failed. Execution failed: Applet thread threw exception: java.lang.RuntimeException: Incorrect drop data: null

The problem is specific for XToolkit. On MToolkit and WToolkit the test passes.

To reproduce the problem I used Gentoo Linux + GNOME.

The problem exists in 1.5.0_04 but I was not able to reproduce it with 1.5.0_02.
