This stack trace looks like it’s during creating a client proxy. Is that something you do a lot? If so, you really should either pool the proxies or use them in some other thread safe manner to avoid creating them all the time. Creating them is expensive and involves several locks. In this particular case, it’s creating a JAXB context. In theory, the context cache can hold onto and share the JAXB contexts between multiple client proxies, but if the proxies are discarded and not held onto, the cache would clear as well and contexts would need to be re-created.
