Most of real world use of Java platform has next to 0 concerns like those. Some more niche use case may benefit, good, but overall success map isn't changing anytime soon. Reasons for its long term success lie elsewhere.
Android Java apps' memory consumption is definitely a relevant concern.
It doesn't even run "JavaTM", but some bastard child that is in like ~5 years delay compared to OpenJDK.
Not true. Lots of large Java deployments with millions to billions in cloud spend. The Java part of it isn’t 0.
Memory isn’t free. CPU isn’t free.
And java uses very little CPU compared to most other languages. It's right after manual memory managed languages like C/C++, and is the first managed language according to a paper about how "green" each language is.
But there is a semi-fundamental tradeoff here, you either use more CPU to use less memory or the reverse. Java can be dynamically configured for either end (though defaults to less CPU by not running the GC unnecessarily).
