NPE Upon Startup

[gorshing]

I have a SpringMVC 3.0.5 app using Hibernate 3.6.1 and it's
AnnotationSessionFactoryBean and when I add <hprof:profiler /> I get
the following NPE.

[09-14 09:09:51] ERROR ContextLoader [Thread-2]: Context
initialization failed

I have tried the following:
<hprof:profiler host="localhost" init-on-startup="false" port="1234"
useSpy="false" />

Hoping that setting all properties would give a different error, but
to no avail. Side note: The documentation at http://hibernateprofiler.com/learn
shows to use "address", but this is not a valid attribute of the
profiler element.

Our AnnotationSessionFactoryBean is set up as an abstract bean with
other bean definitions declaring it as a parent. I'm not sure if this
would make any difference. But I did try and put <hprof:profiler /> in
bean definitions which declare the AnnotationSessionFactoryBean as a
parent, but no difference.

I can provide more information as it is needed.

Can you share your AnnotationSessionFactoryBean definition and the
beans that extend from it? Also, if you do
hibernatingrhinos.hibernate.profiler.appender.HibernateProfilerTrace.setTraceEnabled(true);
somewhere before Spring starts up, I will be able to tell exactly
which bean definition is causing your problem.
