No. They are (B)R java. We are obsoleting older version of java and doing mass rebuild. Thats the 
only way how to ensure whole stack is build by same jdk - main  jdk - and we need to ensure 99% of 
people will be using the correct jdk with correct application

I probably miss your point, you seems to be unaware about haw java udates and stack is working
