While I tend to agree, it's just a losing battle (in my experience). The issue is that shockingly few people in organizations actually care about language improvements. Further, because orgs prioritize spitting out new features above all else, selling maintenance work like updating the JVM is seen more as pure waste than actual benefit to the company.

The one argument I've been able to make to get an update is "This has fallen out of support and will no longer get security updates". That seems to be the only motivator for my company to do updates.
