Firstly, let me assure you that Java is more flexible than C++ concerning your points. You can have multiple inheritance by the use of interfaces, inner classes and abstract classes.
You must also know that a deadly diamond of death is better handled in Java than C++(In C++ you use function calls whereas in Java you use inherited interfaces). Thus, you dont interfere with the object-oriented model.
Also, know that in the following months the new java version will include a more wide version of the C++ templates, generics with which you can have templates. Moreover, you must understand that the game of which language is faster is being heard before.
But know that, you can have Java-code even faster than C++ using static blocks of code and a very fast JVM like hotSpot. Of course, in certain cases only. As i said C++ is only in 30% o.o..
Furthermore, know that Java has about more than 5000 classes enriching its very professional application environment whereas C++ hasnt got any standard libraries except from io streams and stl.
Lastly when you say that java badly supports other languages i dont know if you tried JNI(Java Native Interface) or not. You can have JNI-code using C++ or C function calls or even inside a C++ funtion to have a construction of a JVM use java code and then destroy it.
Know also, that all the scripting languages(and i mean all!!!) can be simulated in java native code.
At the end, i dont understand your last question. If you mean what i use for programming then let me tell you that i use both languages in both unix and microsoft applications.
LET ME ASSURE YOU i dont try to compare the two languages. That would be irresponsible from my part since both languages are used where they better fit. I just try to answer your questions.
Im really interested in your reply!!!

dacs.java
DACS.JAVA(7) DACS Miscellaneous Information DACS.JAVA(7) NAME
dacs.java - DACS Java support DESCRIPTION
This document describes support for Java provided by DACS. To enable Java support, DACS must be configured using the --enable-java flag. It may also be necessary to specify the location of the Java commands and include files. See dacs.install(7)[1]. Note Java support is currently very limited and should be considered experimental. It is currently only possible to call dacsauth(1)[2] and dacscheck(1)[3] using the Java Native Interface (JNI) provided. The command line arguments to both of these commands are exactly as documented in their manual pages. Each argument is passed as a String. The code is not thread-safe and is probably not suitable for being called many times within a particular process due to assumptions it makes about dynamic memory allocation. There are no immediate plans to improve or extend Java support. Using the existing capability to build the JNI layer, however, it should not be difficult for an experienced Java programmer to build upon the example Java code provided. With Java support enabled, building DACS will copy the JNI shared library and a .jar file to the library directory (default: /usr/local/dacs/lib), and the JNI include files to the include directory (default: /usr/local/dacs/include). The tools/java/jni distribution directory contains a simple script called javarun that demonstrates how to run dacsauth or dacscheck as a Java application. For example, to validate the Unix password for user somebody, run (as root): ./javarun dacsauth -m unix suff -user somebody -prompt DIAGNOSTICS
The return codes are as documented in the command's manual page. AUTHOR
