Most such places probably have some trauma related to Oracle now. Someone spun up the wrong JVM by accident and within hours salespeople were on the phone with some middle manager about how they would like to pay for it, that kind of thing. Or just the issue of injecting their surveillance trojans everywhere and knowing they're there, that's pretty off-putting in itself.

Which is a pity, once you learn to submit to and tolerate Maven it's generally a very productive and for the most part convenient language and 'ecosystem'. It's like Debian, even if you fuck up badly there is likely a documented way to fix it. And there are good libraries for pretty much anything one could want to do.
