Caused by: java.lang.NoClassDefFoundError: com/google/gson/JsonParseException ?

I just upgraded to GWT 2.8.2, that works fine.

I just noticed that in case the deobfuscator throws an exception as it can't find the GSON JsonParseException, why is that?

I can't remember that was in GWT 2.8.0, but I am not sure. Neither do I see gwt-server include the gson automatically as dependency when running maven install.

I added it manually to solve it.

For both versions the Maven pom.xml for gwt-servlet artifact declares an optional dependency to GSON. It is optional because it is only needed when you use StackTraceDeobfuscator on the server. So if you use that, you need to add GSON manually to your pom.

Maybe you updated some other libraries too which have included GSON transitively but now don't.

Ok, thanks for clearing that up.
