Java was a direct reaction to C++, not Objective C.
James Gosling's earlier object oriented PostScript based NeWS interpreter was a lot more like Objective C and Smalltalk than his later Java language was. (But I'm not going to mention the earlier abomination that was Gosling Emacs MockLisp. Oops!)

"Java Was Strongly Influenced by Objective-C
...and not C++...
A while back, the following posting was made by Patrick Naughton who, along with James Gosling, was responsible for much of the design of . Objective-C is an object-oriented mutant of C used NeXTSTEP and MacOS X, and also available with gcc."
"In order to supply a comprehensive and flexible object programming solution, Sun turned to NeXT and the two developed OpenStep. The idea was to have OpenStep programs calling DOE objects on Sun servers, providing a backoffice-to-frontoffice solution on Sun machines. OpenStep was not released until 1993, further delaying the project.
By the time DOE, now known as NEO, was released in 1995,[1] Sun had already moved on to Java as their next big thing. Java was now the GUI of choice for client-side applications, and Sun's OpenStep plans were quietly dropped (see Lighthouse Design). NEO was re-positioned as a Java system with the introduction of the "Joe" framework,[2] but it saw little use. Components of NEO and Joe were eventually subsumed into Enterprise JavaBeans.[3]"
While Obj-C had a massive influence to java, I'd not call it clone - even Java 0.9 is a lot better language than Obj-C of 2010 (or so). The saving grace of Obj-C - it could include normal C just like that.
>Although leaving out messaging and leaving in both int and Integer
Both are great choices... from performance point of view. Java is still modeled after plain C 1st and foremost. int should be the default and Integer(and Long) should be avoided. Up to java1.5, it took a manual operation (Integer.valueOf/intValue) to convert, so it was not abused as much. Marked integers have been in the works and they take a significant engineering effort for a nice to have feature.
When collection framework was introduced, it should have had primitive Maps/Lists - there was a regret (around java8 times) not including them initially - Streams attempted to amend the damage. The primitive types map directly to the hardware. Wrapped ones - they are pointer to an immutatable primitive and enjoy little optimization from the JIT.
As for swing, beans and properties - I'd say Delphi would have the most similarities.
