     The question was about time rebuilding JDK after a small change.

    What time does it take to rebuild the official  jdk8/jdk8 forest 
with default options after small change in the java file like 
javax.swing.JFrame ?
    Is sjavac are enabled by default now in the  official  jdk8/jdk8?  
If no,  what time does it take to rebuild the JDK with the 
--enable-sjavac option?

    Thanks,
    Alexandr.
