Java makes me jittery
Java has many features, but it also has a lot of misfeatures. It is also under Oracle's control and that is not something to help me sleep at night.
I did not commit to Java due to its issues. The reason I took Java off of our machines entirely is due to security. I could not in any practical way secure it to my satisfaction.
It looks to me as if a big part of the demand for Java programmers is to clean up the buggy mess left behind by other Java programmers.
