Hi Kerry, Yes it executes in another thread (jetty http executor thread pool), so the context is different.
The code actually fails quite deep in the abyss of the java service loader: Caused by: java.util.ServiceConfigurationError: javax.xml.parsers.DocumentBuilderFactory: Provider org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found at java.util.ServiceLoader.fail(ServiceLoader.java:239) ~[?:?] I should switch the current thread classloader to use the classloader of the class java.util.ServiceLoader? Thanks!!
