[Bug classpath/28998] New: RSSOwl fails to start - hang in ServerSocket accept?

[psj at harker dot dyndns dot org]

RSSOwl (1.2.2 Fedora Extras package) hangs for me at startup with both JamVM
and Cacao against Classpath HEAD where it works fine with Classpath 0.92. Hang
is before splash screen is displayed.

With verbose class loading and capturing a thread dump at hang gives:

1) Cacao:
