Changes how listeners and adapters are managed

[masesdevelopers]

Description

Changes how callbacks are managed returning a boolean value indicating if .NET has done an override. Then, if .NET hasn't done the override, in the Java side:

• if the method belongs to an interface:
  • if there is a default implementation execute the default
  • otherwise throws an UnsupportedOperationException
• if the method belongs to a class:
  • if the method is declared abstract throws an UnsupportedOperationException
  • otherwise execute the super class method

Warning

It can introduces a breaking change since Java methods request to be implemented in .NET if:

• belongs to an interface and do not have a default implementation
• belongs to a class and are declared abstract
