Should it be pointed out that none of the open source vms can properly be called "Java" as none of them have passed sun's specification test? —Preceding unsigned comment added by 74.114.186.166 (talk • contribs) 08:01, November 2, 2006

Although the Microsoft JVM is discontinued, only supported 1.1, and had proprietary extensions, it was still notable because it was for many PC users the only VM present on their computer (although Dell and HP started shipping VMs around 2003 with their computers.) Perhaps this should go under a "historical" section? —The preceding unsigned comment was added by ItsProgrammable (talk • contribs) 21:34, 29 January 2007 (UTC).[reply]

I think it should be noted in which language the JVM is written. Is there a JVM written in Java? 85.228.22.167 (talk) 22:22, 8 June 2008 (UTC)[reply]

Why Sun JVM not present?????? —Preceding unsigned comment added by 87.218.157.254 (talk) 10:33, 2 April 2010 (UTC)[reply]

Why is there a subsection "Lesser-known proprietary Java virtual machines"? The selection seems kind-of arbitrary (Imsys SNAP seems to be a lot less documented than, for example, Blackdown Java). I'd argue that the heading should simply be removed. Rentar (talk)

Should this list mention the ZERO VM? The Zero VM is created to be portable in the sense that it contains zero-assembler code. Maybe I just missed the entry, but I expected a find command on "zero" in the browser window to succeed. Ormek(de) 62.112.80.99 (talk) 09:38, 30 August 2011 (UTC)[reply]

Dalvik isn't a JVM, and is certainly not licensed. Dalvik uses its own byte code that is incompatible with Java byte code. Cross-compilation support shouldn't be enough to make a virtual machine pass as a JVM. No one would argue that V8 is a JVM just because we can use GWT to get Java->Javascript. Please remove it from the list (although it is a technical achievement on its own, it's simply not a JVM). — Preceding unsigned comment added by 213.113.183.85 (talk) 20:17, 9 June 2013 (UTC)[reply]
