Hi Bruno,
Yep it is indeed based on the OpenJDK source code. However it looks to be
provided by Oracle (and hence falls under the oracle licence):
%docker run -it --entrypoint '/bin/bash'
gcr.io/cloud-dataflow/v1beta3/beam-java-streaming:2.46.0
WARNING: The requested image's platform (linux/amd64) does not match the
detected host platform (linux/arm64/v8) and no specific platform was requested
root@e8dfe675ad85:/# java -XshowSettings:properties -version 2>&1 | grep vendor
java.specification.vendor = Oracle Corporation
java.vendor = Oracle Corporation
java.vendor.url = http://java.oracle.com/
java.vendor.url.bug = http://bugreport.sun.com/bugreport/
java.vm.specification.vendor = Oracle Corporation
java.vm.vendor = Oracle Corporation
(The eclipse runtimes vendor, as used in beam_javaX_sdk, are set to Temurin
with adoptium url’s.)
I’m unable to find the docker file to see exactly were the runtime is being
sourced from.
Thanks
Hardip
