thanks for your fix and your contribution.

Unfortunately, we want to change the License and have to wait till we can merge this request.

If the License change is done I will cherry-pick this in our internal repo merge it and then it will be mirrored back to this repo.

with commit 9b0de96c4699dfeeed41792c205c52eb8d5d20de we changed the license to Apache 2.0

Are you still fine with merging it under the new license? In this case, we would cherry-pick it into our internal repository and merge it.
