ZK Studio

Trying to get ZK Studio running for a couple of days on Eclipse 3.3, 3.4,
and 3.5. They all give me an "Unhanded event loop exception" when ever I
try to open a ZUL document.

System Information (Eclipse 3.5):

eclipse.buildId=I20090611-1540
java.version=1.5.0_19
java.vendor=Apple Computer, Inc.
BootLoader constants: OS=macosx, ARCH=ppc, WS=carbon, NL=ja_JP
Framework arguments: -product org.eclipse.epp.package.jee.product -keyring
/Users/*username*/.eclipse_keyring -showlocation
Command-line arguments: -os macosx -ws carbon -arch ppc -product
org.eclipse.epp.package.jee.product -keyring
/Users/*username*/.eclipse_keyring -showlocation

I wasn't asked for login information on Eclipse 3.3, but when asked for it
on 3.5 I entered my ZK username and password then the following exception
was thrown. The only way to continue on was to say "Skip for now."

When I tried to open a ZUL file in the editor again, I got a similar
problem in Xerces:
