Hi Ales,

We finally tried CapeDwarf again after 2 years. We fix many issues in GAE4J itself, thanks to a better warnings by CapeDwarf. But we are stuck here with the error in the subject with some of our APIs. Could you advise us on what might be wrong? Some info that might help:

JAVA_HOME=C:\jdk1.7.0_51

GAE_JAVA_SDK_HOME=C:\appengine-java-sdk-1.9.12

Windows 7

Latest CapeDwarf (CapeDwarf_WildFly_2.0.0.Final), running locally not on PaaS like OpenShift

The full logs is as the following:
