get App Inventor working with OpenJDK

[GoogleCodeExporter]

The official documentation includes this warning

I'm having various Java problems, and I'm running on Linux and OpenJDK.

Use Sun Java rather than OpenJDK. App Inventor does not work well with OpenJDK.

It would be very nice if App Inventor worked with OpenJDK.

You have more experience with OpenJDK than we do.   Could you try running App 
Inv with OpenJDK and see if it works?    When  tested it last summer, there 
were problems with sluggish behavior, for example, on opening and closing 
drawers in the Blocks editor.   Maybe OpenJDK has improved to the point where 
things now just work, or there is some Java  parameter setting that's required. 
   Could you check?

Love to.

I have two more Linux machines up (getting ready for a workshop) and tried it 
on both.

I have NOT installed extras on them
  yet

I'm starting to use Linux again. I was doing most of my work in Windows because 
that is where most of the getting set up and connecting issues are reported. I 
did some testing with a wubi Linux distribution. It looks promising for some 
AND I did not find OpenJDK to be sluggish. In fact someone said it looked 
faster than on his more powerful PC.

I'll probably not report back here unless you want me to. I will let the 
community know how it goes.

I am reviewing some of the issues on the Google App Inventor list to see how 
the MIT jars do. That includes doing more Linux work. I tested with OpenJDK and 
it works fine for me.

I think this should be closes,
  or at least marked as works for Gary.

The problem that I've noticed with OpenJDK 7 was that you couldn't join two 
blocks together. They overlay, though never connected.  This problem wasn't 
experienced with Oracle JDK 7.

Tested on Ubuntu 12.10 x32, FF17 and:
$ /usr/lib/jvm/java-7-openjdk-i386/bin/java -version
java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.3) (7u9-2.3.3-0ubuntu1~12.10.1)
OpenJDK Server VM (build 23.2-b09, mixed mode)
$ /usr/lib/jvm/java-7-oracle/bin/java -version
java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) Server VM (build 23.5-b02, mixed mode)

I have used Ubuntu 12.04 64 bit with OpenJDK 6 and 7 a LOT in the last year.

Try using Chromium rather than FF.
