Google App Engine now supporting Java virtual machine
Google’s just released a Java 6 virtual machine on their Google App Engine platform. It’s a sandbox environment that wraps the Google services in standard Java interfaces that should be able to run most libraries with some tweaks.
This is pretty huge, because depending on how restrictive the sandbox is we could run Scala, Groovy, Jython, JRuby, etc. on top of the same VM. Now if I can just get my head around non-relational databases.
