working with types in java namespace

[jmayclin]

I want to expose the following method, but I'm uncertain whether this is possible.

public javax.net.ssl.SSLEngineResult wrap(
    java.nio.ByteBuffer, 
    java.nio.ByteBuffer
) throws javax.net.ssl.SSLException;

The duchess::java module does not expose any of the nio types. I can write my own bindings for java.nio.ByteBuffer, but I can't figure out how to refer to that in my javax package.

duchess::java_package! {
    package javax.net.ssl;
    class SSLEngine {
        public javax.net.ssl.SSLEngineResult wrap(java.nio.ByteBuffer, java.nio.ByteBuffer) throws javax.net.ssl.SSLException;
        public abstract java.lang.String[] getEnabledCipherSuites();
    }
}

This results in the following error

   --> bench/src/coffee/java_def.rs:227:5
    |
227 |     class SSLEngine {
    |     ^^^^^ could not find `nio` in `java`
    |
help: consider importing this module
    |
187 |     package javax.net.use crate::coffee::java_def::java::nio;
    |                       +++++++++++++++++++++++++++++++++++++++

While maybe I could bring my own java package into scope, I still need access to the duchess::java package for java.lang.String[] and other similar types.

Yes, we need a general solution here for some sort of merging of packages by duchess. Maybe this is more practical now that we have build.rs?
