[BUG] [JAVA] JSON SubType case wrong in Java class reference

v3.3.4

yaml below produces a class "MyEvent" (.java) - initial letter capitalized -, but consumes that very class with lower-case (e.g. myEvent.class).

Steps:

• generate for Java
• mvn clean compile

// exp: compiles
// act: breaks "cannot find symbol symbol: class myEvent"

Root cause is apparently that code generator does capitalize, but that this capitalization is not sent into all dependent generators.

Start with the supplied Swagger YAML and generate the Java client, then run mvn clean compile to reproduce the myEvent versus MyEvent reference error. Trace how the Java generator propagates model names to dependent generators; done means the generated Java sources compile and consistently use the capitalized class name.
