host_javabase is deprecated

[juanpmarin]

Since bazel 5.0 the parameter used here is deprecated:

reactive-grpc/bazel/java_reactive_grpc_library.bzl

Line 74 in 071f153

host_javabase = find_java_runtime_toolchain(ctx, ctx.attr._host_javabase),

Generating the following error:

Traceback (most recent call last):

		java_info = java_common.compile(
Error in compile: in call to compile(), parameter 'host_javabase' is deprecated and will be removed soon. It may be temporarily re-enabled by setting --incompatible_java_common_parameters=false

The documentation suggests that it can be just dropped:

Do you find any risk on doing this?

I'm not sure. I'm not really a Bazel expert. If you drop this, does everything Bazel still work?
