Lets make all languages as abd as Java?
Why should I run my superbly portable programs written in perl, php, python ruby etc. on an unreliable, badly performing and not very portable JVM?
php and python have superb native implementations on any platform you are likly to use so the only point of running inside a JVM is to get access already written java classes.
But this is a very unusual situation if you are not a Java programmer given the vast number of standard and extension libraries available in most scripting environments.
The only good thing about this is that it will perhaps give the Java bigots a chance to program in a decent language and wean them away from thier do nothing factory classes and thier thousands of lines of try/catch/throws that surround any useful piece of code.
