Welcome to LabsJDK CE 11.
The latest release is available at https://github.com/graalvm/labs-openjdk-11/releases/latest
This is a fork of https://github.com/openjdk/jdk11u-dev (which is a read-only mirror of https://hg.openjdk.java.net/jdk-updates/jdk11u-dev/) that exists for the purpose of building a base JDK upon which GraalVM CE 11 is built.
It can be built with:
python build_labsjdk.py
This will produce a labsjdk installation under build/labsjdks/release along with 2 archives in the same
directory; one for the JDK itself and a separate one for the debug symbols.
You can verify the labsjdk build with:
./build/labsjdks/release/java_home/bin/java -version
The original JDK README is here. Further information on building JDK 11 is here.
