We have seen Jetty having problems with class loading that resulted in
deadlocks.  Could you please try the following.  Fetch Jetty's sources,
edit file src/org/mortbay/http/ContextLoader.java
and remove "synchronized" word from both loadClass() method, then
compile this single file and replace it in jetty's jar (or alternatively
you can of course rebuild whole jetty, but it is possible to only
rebuild this single file).

If you built with the defaults, it Should Not(tm) be the case, but...
Can you please remove ${prefix}/share/sablevm-classpath/*.jar files
and reconfigure/rebuild sablevm-classpath with this option:
	--disable-compressed-classes

This should result in class files being put directly on-disk, just
like it was in 1.1.6 and previous versions.  Note that I have not
(personally) tested this option, so in the worst case you might need
to set sablevm.boot.class.path property to point to where the classes
are installed.  Or you could simply unpack the two .jar files you have
now to a single directory and set sablevm.boot.class.path to point to
it - and then retry running your app.

Thank you very much for your report.

Let us know how it went,
