We've come across a problem in Camel 2.7.1 where Camel fails to start up
due to a TypeConverterLoaderException. This is a regression, as we've
had no such problem in Camel 2.5.0. Is this a known issue? Googling
around, I've found [1], which states:
My second problem is that it's currently not possible to start camel
without the AnnotationTypeConverterLoader added. In case of a webstart
based client application this causes startup errors that prevents using
camel.
I added an attribute to suppress the usage of
AnnotationTypeConverterLoader in my local sources and I've prepared a
patch for this problem and the problem described above with test case.
Should I create a JIRA issue?
I can't say that I understand his description of the problem or his
fix. Has a jira issue been created?
My reproduction is simple:
public static void main(String... args) {
try {
CamelContext context = new DefaultCamelContext();
context.getTypeConverterRegistry();
LOGGER.info("Success");
}
catch(Exception e) {
LOGGER.error("Failed", e);
}
}
This runs fine in my ide and fails with [2] when deployed via webstart.
Thanks,
Jim
