Null pointer when parsing camelContext.xml file during startup

[bretpub]

Does anyone have any ideas on this one?  This is an intermittent problem.  Starts sometimes np, othertimes consistent error.  Almost like a timing issue on loading beans.

P.S.  my context file is further down.

Removed route and still having issues

turns out I had the jaxb-impl.jar file on my classpath and it was colliding with another jar somewhere, and when I removed it the parsing troubles vanished.  Now I just have to figure out where the other jar it is colliding with is.

I also experience this intermittent problem when using Spring XML to define the routes.

[jradecki]

++2 intermittent under Core and Tomcat as well;  annoying isn't it.  Think it's a bootstrap threading issue w/Spring...

[andrew.mann]

I'm also experiencing this with camel dsl routes, how did you isolate the issue to the jaxb jar? Have you seen the problem since?

backing my JDK down from 1.7 to 1.6u30 has fixed this issue.

[fabdouglas_fabrice.daugan]

Even with 1.6.0u30, I ahve "sometimes" this NPE.

[fabdouglas_fabrice.daugan]

I've moved down from jaxb-impl-2.2.4 to jaxb-impl-2.2.3.

Even if after a dozen of tests I've no more NPE, it may back later...

Good to know. Also I noticed in the 1st post that the application is running on Windows in a directory which has spaces (eg Documents and Settings). Its generally not a good idea to run stuff in directories with spaces.
