Bump Java language level to Java 17 per default Note that with this change CI verification takes place on JDK 17 for both checker environments: Build/Tests and RBE Build/Tests. Also update eclipse project generation to reference JavaSE-17 per default. Also change compatibility mode of Locale Sensitive Service Provider to COMPAT only, as it also fixed the tests on Mac Os X operating system. Test Plan: To build with Remote JDK 17 locally: $ bazel build release To build with Remote JDK 17 on RBE: $ bazel build --config=remote --remote_instance_name=<name> release To build with Remote JDK 11 locally: $ bazel build --config java11 release To build with Remote JDK 11 on RBE: $ bazel build --config=remote11 --remote_instance_name=<name> release Release-Notes: Update Java language level to Java 17 per default Change-Id: I932527e6036efb1518a31979a22a086e458bbc5c
