gwt-log v3.3.1 and GWT SuperDevMode

[Dennis Foster]

Anybody got gwt-log working with GWT SuperDevMode using the latest versions of both (gwt-log v3.3.1, GWT 2.6.1)?  

When I try to start my Eclipse debug configuration for SuperDevMode with the v3.3.1/v2.6.1 combination, I now get the following error and the debug session won't start.

Loading inherited module '...this is the name of my module file...'

   Loading inherited module 'com.allen_sauer.gwt.log.gwt-log-DEBUG'

      Loading inherited module 'com.allen_sauer.gwt.log.gwt-log-impl'

Note that I had this working most recently using gwt-log v3.1.8 and GWT 2.6.0.  I'm using the same debug configuration now as I was with the earlier version combination.  If I remove the gwt-log stuff from my module XML (and remove the code references), SuperDevMode works fine.

51.0 is Java 7.

Are you trying to build with Java 6?

Actually, I'm building with Java 8 (v1.8.0_11).

[Fred Sauer]

What happens if you target Java 7 for your build?

My problem was caused by the version of Java Eclipse was using.  Although my execution environment and build scripts use Java 1.8.0_11, Eclipse itself was using a 1.6 JDK.  Once I corrected that, all is working.

Thanks!
