The code is trying to ascertain that it can set system
properties. This line is the culprit:
// attempt to improve initialization performance
Introspector.setBeanInfoSearchPath(new String[0]);
See if you can allow setting system properties in
your Tomcat's policy file. Note: I'm not a Tomcat
expert, and I've never seen this issue before with
UIMA and Tomcat 5.5.
