;-) I may ask around. In general I don't feel responsible for testing my 
application against newest JDK when I have not changed a single line of code. 
I believe it is upstream project responsibility to not break us.

I don't necessarily want every JDK engineer to test with NetBeans, but when it 
is known there was a problem with NetBeans build (because of changes in JDK 
code), I would expect the verification to be done by JDK engineer prior to 
announcing "something is fixed".

Do I require too much? Building NetBeans is matter of three commands. Did our 
engineers forget to mention those commands when they complained about NetBeans 
build being broken? If so let me know, and I make sure they get fired.

100% backward source compatibility is hard to achieve in Java, so yes, we can 
accept some changes. The requirement however is to find a way to write the 
source so it compiles on JDK7, JDK8 and JDK9 at the same time. Will that be 
possible?
