You are pointing at the fastdebug jdk as your boot jdk, why?

The official boot jdk for jdk8 is jdk7u7 we cannot guarantee anything else will work, although it should, when tracking down issues like this, you need to narrow down all the possible differences. I have no idea at this time what the 'sync state' is with the awt team forest. My recommendation would be to clone the official jdk8/jdk8 forest, which can be assumed to work since RE should have built it, or any integrator pushing changes into it should have built it. Create 2 forests of so you can do separate experiments on each. 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.

Then do the build from the root with a 7u7 jdk in your PATH (no need for the --with-boot-jdk option). Do a build without --enable-sjavac on one forest, then with it on the other.

You can try by adding --enable-sjavac to configure and do a clean build. If the build works, you have it, and incremental builds will be much faster. I tried to use the --enable-sjavac option and JDK 7 and 8 as a boot JDK. --with-boot-jdk=/cygdrive/c/Sun/Tools/JDK/jdk7/7u14/b10/jdk1.7.014/fastdebug --with-target-bits=32 --enable-sjavac gives compilation error

--with-boot-jdk=/cygdrive/c/Sun/Tools/JDK/jdk8/b75/jdk1.8.0/fastdebug --with-target-bits=32 --enable-sjavac gives "OutOfMemoryError: Java heap space" error. The log files are attached. Thanks, Alexandr.

What kind of change did you do? Was it in native code or java and in which repository? I use the http://hg.openjdk.java.net/jdk8/awt repository, edit java code and build the jdk. To reproduce the issue: - open the javax.swing.JFrame class and add a comment line: // a comment - build jdk ----- Build times ------- Start 2013-02-11 15:09:55 End 2013-02-11 15:17:08 00:00:03 corba 00:00:02 hotspot 00:00:01 jaxp 00:00:03 jaxws 00:06:54 jdk 00:00:02 langtools 00:07:13 TOTAL ------------------------- My environment: OS: Windows 7 Professional, x64 Processor - Intel Core i7 Memory - 8 GB The log file is attached.
