--------------------------------------------------------------
I fix this issue by compute the "digest" in the constructor of RexCall.One
problem for this PR is that the "computeDigest" may call twice in the
constructor for RexOver which overwrite the "computeDigest" method and must be
called after the "window" has been prepared. The PR is here
[PR873|https://github.com/apache/calcite/pull/873].
Please have a check,thanks!
