I have this problem too.
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)
The behavior is similar like in this issue https://issues.apache.org/activemq/browse/SMX4-326: (examples-cxf-wsdl-first-osgi-package work until you restart smx) except couple of things:
1) When smx goes down one exception is thrown http://pastebin.com/raw.php?i=kHb8Ja9u
2) Next time when you start smx there are no any exceptions in log.
3) It's seems that after restart, the ServiceMix :: CXF Binding Component (2010.01.0.fuse-02-00) wont start correctly, because there is no more OSGi service exposed by ServiceMix :: CXF Binding Component (2010.01.0.fuse-02-00) bundle.
When I typed ls 135, I had no output information at all.
However before deploying examples-cxf-wsdl-first-osgi-package I had the following info about ServiceMix :: CXF Binding Component (2010.01.0.fuse-02-00) http://pastebin.com/raw.php?i=2mzeVFf1
