GWT 2.70 and emulated compiler stack mode

[James Bearden]

Hello,

My client application talks via JSON to a non-Java based server, and up until GWT 2.6.1 I was using the "emulated compiler stack mode" feature to generate a stack trace when the client had an exception and then submitted it via a JSON request to be logged on the server. Thankfully it doesn't happen very often, but when it does it is incredibly useful to have that stack trace. Unfortunately that feature doesn't appear to be working with GWT 2.7.1. Can anybody offer any advice as to how I can get it working, or what a viable alternative might be?


In my gwt.xml I had the following:

  <set-property name="compiler.stackMode" value="emulated" />
  <set-configuration-property name="compiler.emulatedStack.recordLineNumbers" value="true"/>
  <set-configuration-property name="compiler.emulatedStack.recordFileNames" value="true"/>


TIA,

James

Whoops, to be clear, it was working up to and including GWT 2.6.1, but has stopped working in GWT 2.7.0.

What does "does not work anymore" mean? The exception does not have a stack trace? Or a wrong stack trace? Or you can't send it to the server anymore? Or something else?

Given that emulated stacks are generated by the GWT compiler it might be a regression bug, but you have to be more specific about what's wrong and then open an issue.
