Possible CORBA Workaround for Domino Java

[JoelProminic]

Previously we saw that Java Domino applications need to be compiled with JDK 8 in order to avoid CORBA errors. See #1124:

> Task :compileJava FAILED
/Users/joelanderson/Downloads/DxlImporterTestDemo/src/main/java/DxlImporterTestDemo.java:94: error: cannot access UserException
        try {
        ^
  class file for org.omg.CORBA.UserException not found

@feather812002 found a workaround for this where we include this library. In Gradle, I can do this with a dependency like this:

	// work around the org.omg.CORBA.UserException error
	implementation 'org.glassfish.corba:glassfish-corba-omgapi:4.2.4'

In my initial tests, this avoided the error, and it hasn't triggered any other problems so far. I'm still building the project in 1.8 compatibility mode:

sourceCompatibility = 1.8
targetCompatibility = 1.8

This needs more testing, but it could allow us to move to newer SDKs.
