Chrome is at a position which IE6 used to be. They don't care.
They first killed NPAPI plugs so that Java Applets don't work. So we moved to JNLP. Then they have a bug by which JNLP cannot be autolaunched in Chrome like it can in IE & Firefox. So if it's a weblaunched JNLP, users have to save the JNLP file & then run it which is troublesome for a lot of lay users. This bug exists for 4-5 years & there are multiple bug ids for it. But it never get fixed. Then there is another bug by which when you save the JNLP files after 99 JNLP files - no more can be saved & or run.
Chrome doesn't care to fix these bugs because what do they lose if they don't fix it.
