Hi Christian,
As camel used widely in OSGi container and next Servicemix 4.4 release
target to use camel 2.8.0, without this fix it means any camel bundle
with src/main/resources/META-INF/services/org/apache/camel/
TypeConverter can't work in OSGi container, IMHO this is a critical
issue camel team should address before release.

I think this issue is quite a bit ugly in OSGi but I think it does
not absolutely warrant a new release.
What do others think?

Hi Team,
Figured out this was caused by improper call
BaseTypeConverterRegistry.loadTypeConverters() in OSGi container,
which throw exception and prevent Activator in camel-core to get
chance to load type converter from bundles, so it's may not only
affect the JBI example I mentioned before , create CAMEL-4231[1] to
track it and patch appended.
Could someone kindly review and apply this patch if it's ok?

Hi Team,

I found one issue that when I try to deploy camel and bridge-camel
example shipped with servicemix4 kit.

But in the org.apache.servicemix.camel.converter(it's servicemix-
camel jbi component code base) package, there is a JbiConverter[1]
class which has converter annotation, seems it's another
classloader issue due to recent change in camel. I'm not sure if
we can workaround it on servicemix side now, so I have to say -1.
