getInstance

                      Object rawJavaObject,
                      boolean forceCache)

Returns a new proxy instance of a type corresponding to rawJavaObject's class, or the cached proxy if we've already seen this object. Note that primitives and strings are not coerced to corresponding Ruby types; use JavaUtil.convertJavaToUsableRubyObject to get coerced types or proxies as appropriate.

Parameters:

runtime - the JRuby runtime

rawJavaObject - the object to get a wrapper for

forceCache - whether to force the use of the proxy cache

Returns:

the new (or cached) proxy for the specified Java object
