Hello,

With the JDK 11 and 12 split fast approaching [1], it is time to work on the various start of release update tasks for JDK 12. Those tasks are being tracked under the umbrella bug JDK-8205615: "Start of release updates for JDK 12". This thread is to review the build-related portions of the work including JDK-8205621: "Increment JDK version for JDK 12." Current webrev: http://cr.openjdk.java.net/~darcy/8205615.4/

make/autoconf/version-numbers

If we're going to ensure we bump the version and classfile version together then we should be able to restore:

DEFAULT_VERSION_CLASSFILE_MAJOR=56 # "$EXPR $DEFAULT_VERSION_FEATURE + 44"

to just:

DEFAULT_VERSION_CLASSFILE_MAJOR="$EXPR $DEFAULT_VERSION_FEATURE + 44"

Possibly we could also set:

DEFAULT_ACCEPTABLE_BOOT_VERSIONS

to use DEFAULT_VERSION_FEATURE, DEFAULT_VERSION_FEATURE-1 DEFAULT_VERSION_FEATURE-2 ? If that is our boot JDK policy. Or will we drop 10 at some point in the process?

make/common/SetupJavaCompilers.gmk

Again if we're bumping everything en-masse can we use DEFAULT_VERSION_FEATURE instead of hard-wiring 12?

And should these be using --release instead of -source + -target?

Thanks, David

A handful of test failures still need to be addressed, so there will be some minor adjustments to the aggregate set of changes before they are pushed.
