Ant target java2wsdl running in Intellij 9 never stops executing

Hi

My ant build file contains a target that uses the ant task java2wsdl and when executed in the command prompt, using Ant of course, works fine

But when I execute the same Ant target inside Intellij 9, that task never stops executing. Nothing happens?!

Output
...
