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

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.
