Wait until you hear about COBOL still being used.

Snark aside, the problem with Java in the enterprise is that Oracle provides support for mind-bogglingly ancient versions (if you're willing to pay them). This disincentivizes companies from upgrading, ends up frustrating their developers, and has probably contributed to the negative reputation that Java has in some corner of the net.

I get that tracking the current version isn't feasible for most companies, especially if software isn't their core business. The Java folks do their best to make upgrades painless, but the longer you wait, the more painful it gets.
