[IDEA] Auto complete Java native and 3rd party libraries

[phommata]

Is your feature request related to a problem? Please describe.
It is slow to develop in Java without the native and 3rd party library completion. I understand that Mirth is not an IDE. Auto complete only supports JavaScript and the Mirth libraries.
 
Describe your use case
I need this feature so I can develop in Java quickly, productively, and efficiently without looking up everything in the Java Docs.

Describe the solution you'd like
Auto complete to support native Java and 3rd party libraries.

Describe alternatives you've considered
Guidance on adding Java autocomplete as needed if there is a way.

Additional context
None.
