Re: Error when obfuscating a gwt jar

External obfuscation seriously interferes with GWT.
1.Whatever is in client package, in any case, can not be obfuscated.
2. All the shared classes undergoing serialization can not be
3. All the classes, which reside only in server, are under your
control and, hence, there is no need for any obfuscation.

If the jar file you are talking about is a thrid party jar, you really
have a problem. When there is an update of jar file, it will result in
an incompatible serialization of the already saved objects.
