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

[shoffmeister]

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.
