unmarshal hangs camel process if using true/false on int field

[dbrmantech]

Recently upgraded to karaf 4.4.6 and camel 4.7.

We found out the hard way that we had some bugs in our XSLT. It was generating XML like this:

<ITAsset (snip)>
	<vulnerability>
		<exploitAvailable>false</exploitAvailable>
	</vulnerability>
</ITAsset>

exploitAvailable in the vuln bean is an int. Oops.

We unmarshal to our java objects like this in our XML blueprints:

	<unmarshal>
		<jaxb prettyPrint="false" contextPath="foo.model"/>
	</unmarshal>

With true or false, It just hangs silently, never returns. If we pass an int, all is well.

Is this a known issue? Is there a work around or some config we could set so if we goof again, it gives us some error message instead of a silent hang?
