> I find this issue as my locale environment is zh_CN.UTF-8 and the javadoc generate the "lang=zh" html files. And this causes the following exception

> This assumes that the java html doc is generated by English language. The workaround could be set "LANG=en_US.UTF-8" when running the maven build. In the other hand, I think it could add "<locale>en</locale>" in the javadoc configuration as we have to depend on the html files. This would effect the camel-as2, camel-linkedin, camel-box, camel-fhir, camel-olingo2 and camel-olingo4.
