Julian Hyde commented on CALCITE-5820:
--------------------------------------
[~Runking], Could you discern why [~vlsi] added {{java.net.URL.getPath}} to the
forbidden list in CALCITE-2495? If there was a legitimate reason, I want to
preserve that; but I also see the value in replicating Hive's implementation of
the function.
