I'm using Java to access 619 from the downloadable install set.
I try to use getProperties() at a newly created text document and get a 
java.lang.InterruptedException. Here is my example.

I've connected to a running office instance and used the servicemanager to get 
the desktop, then the componentloader to load a new writer document to a 
variable oUnoObject. Next:

XPropertySet xPropertySet = (XPropertySet) UnoRuntime.queryInterface
  (XPropertySet.class, oUnoObject);
XPropertySetInfo xPropertySetInfo = xPropertySet.getPropertySetInfo();
Property[] mProperties = xPropertySetInfo.getProperties();
for (int l = 0; l < mProperties.length; l++) {
  System.out.println("." + mProperties[l].Name + "<BR>");
  }

The exception occurs when I call getProperties(). Seems to be a bug, right? 
I set it to prio 4 because I need this for the instance inspector mentioned on 
http://udk.openoffice.org/common/man/tasks.html.

Here's the callstack:
