[jboss-dev-forums] [Design of JBoss Remoting, Unified Invokers] - NPE in HTTPSClientInvoker.

[ddunkin]

I get a NullPointerException at HTTPSClientInvoker.createSocketFactory() line 144 because the code catches an exception and tries to log it, but the logger hasn't been initialized yet. This NPE masks the original exception (which is "java.io.IOException: Error initializing socket factory SSL context: Can not find truststore url." in this case). Maybe the log variable should be static in HTTPClientInvoker.

Here's the stack at the NPE:
