Irony Not Dead, Java Edition
Eclipse launcher (which is written in C/C++) reads the JVM vendor and if it detects a Sun JVM, it adds a necessary memory parameter for Eclipse to function. Since now the "Java" vendor was changed from Sun to Oracle it crashes. So the current version of Eclipse does not work with the current version of Java on the most popular platform - at least not out of the box.
You have to admit, that's kind of amusing :)
