I have tried both jdk8/tl/jdk and jdk8/jdk8/* (with the changes from 
jdk8/tl/jdk pulled in) an in all version it was printed the old 
serialVersionUID. But never mind, I maybe have done something wrong.

But this only protectes for forget of defining an explicit 
serialVerionUID, not an change in it. Or do you think if there is an 
explicit serialVersionUID then the change in it would be noted while 
reviewing?

Maybe an script that collects all serialVersionUID of the classes in JDK 
can compare it with the new ones and print it for documentation (break 
in compatibility). Or is there a real strict "don't break compatiblity 
ever" policy in jdk developement?
