We create antlr4 plugin factory via the following code in `Antlr4Util`:
Antlr4PluginFactory antlr4PluginFactory = (Antlr4PluginFactory)
ParserPluginFactory.antlr4(configuration);
The `antlr4` method is `static`, its implementation is to `new
Antlr4PluginFactory` instance, and the method can not be overrided by
`ParserPluginFactory` subclasses.
public static ParserPluginFactory antlr4(CompilerConfiguration
compilerConfiguration) {
return new Antlr4PluginFactory(compilerConfiguration);
}
So I wonder how to reproduce the `java.lang.ClassCastException`...
