All non-trivial applications, these days, are multi-lingual. For example, 
many applications use a markup language (HTML, RC, etc...) to paint their 
GUIs. Then they use an OO language for their high-level command-and-control 
code (such as Ruby). Then they use a declarative language, such as SQL, to 
interface with their systems, such as OSs and database engines written in a 
C language.

That's because Java was invented to take market share from C++, allegedly 
without introducing new risks. The actual result was a language that's 
harder to compile, and harder to program. Java strongly resists high-level 
abstractions, forcing you to write line after line and page after page of 
cruft just to get anything done. (No wonder the book /Refactoring/ uses 
Java!!;)

Java is hostile to both the CPU and the programmer. Hence, the user suffers 
too.

No prob. Just remember that C++ is "portable OO assembler", and it is 
CPU-friendly and programmer-hostile.

Ruby, by contrast, is the ultimate in programmer-friendliness. At 
considerable expense to the CPU!

Incorrect. C++ is a systems language (per Bjarne Stroustrup, its author). 
Systems are large and long-lived. Nobody is phasing them out.

C++ is strongly represented in the database, videogames, operating systems, 
scientific, and research spaces. Also, all those spaces typically "alternate 
hard and soft layers", by augmenting their C++ with a soft OO language. 
Videogames use LUA, OSs often use Perl, databases use at least SQL if not 
more, and so on. Ruby makes an _exquisite_ soft-layer, to provide the 
high-level features for a C++ application.

Learn to learn languages. I could write a program in Java if you forced me 
to (and with steady access to Google). Then learn all of them. You don't 
have to worry about running out of room in your brain!

You will never miss anything (except lots of entry-level jobs that nobody 
should want) if you avoid Java like the plague, and stick with languages 
that are technically superior. Put another way, the simple motivation of 
having a boss order you to use Java is not good enough. The motivation 
itself will not magically make Java more productive. It will slow you down. 
Some people work by the hour, so that's okay for them. If you want to be 
rewarded for productivity, go with the most technically advanced system you 
can.

I work to the story-point. That means I estimate for my client each feature 
in "ideal hours", and then I charge to those point, _not_ the actual hours 
spent researching and coding. I don't actually give a darn what that time is 
(and it usually includes lots of bizarre interruptions from my females!).

If I did that using any system besides Ruby (on Rails, and pure Test Driven 
Development), I would be absolutely screwed. Instead, I am able to fix the 
cost of each iteration, while keeping the quality as high as possible, 
without excessive delays.
