Re: What are legal "user.agent=" values?

But only to now getting stuck with: 
[INFO] --- gwt-maven-plugin:2.10.0:compile (default) @ zhquest-web ---
[INFO] Compiling module ch.zh.ksta.zhquest.ZHQuestWebDevelopment
[INFO] [ERROR] Unexpected internal compiler error

Now you have conflicting versions of ASM in your class path. The IllegalArgumentException within ASM's ClassVisitor class constructor is usually thrown when you have a class file compiled with a newer Java version than ASM supports. So I guess you have a relatively old ASM version on classpath. GWT itself depends on ASM 9.2 (see: ). ASM 9.2 supports java up to version 18.
