Fail to serialize NoViableAltException

[jbnas]

Attempting to serialize a NoViableAltException, or an Exception whose cause chain contains an instance of NoViableAltException fails because the ctx member (RuleContext) from parent class RecognitionException is not serializable.

Need to make the ANTLR classes that can be included in ANTLR exceptions serializable, or need to make the members of these classes in ANTLR exceptions transient.

public static class GSContext extends ParserRuleContext {
...
}
