DocPlugin 0.9.4 problem on #648

Build #648 Windows 2000 Sun JDK 1.4.0_01

It appears that I can no longer build indexes. Under Project Properties |
Javadoc Plugin, I select the entries I want the index on and click OK. The
dialog appears stating it might take 5 minutes and I click OK. It
immediately comes back and if I check the system/docplugin directory, a
directory for the project has been created, but it is empty.
