All I'm doing is persisting an entity in the datastore. No biggie. And
now I get this super weird error. What is the deal here?
I have no idea how to fix this, especially when the stack trace says
that some code is calling some code "which should be impossible." Has
anyone run into this problem and / or know how to fix?
The culprit code:
Message message = new Message();
message.setActionPlan(actionPlan.getKey());
message.setBody(new Text(body));
message.setCoach(actionPlan.getActionPlanScript());
message.setCoachName(actionPlanScript.getName());
message.setMedium(Notifications.Medium.ANDROID);
message.setSubject(subject);
message.setUser(user.getId());
messageManager.saveMessage(message);
Here's the stack trace:
javax.servlet.ServletContext log: Exception while dispatching incoming
