Was the following assessment in the bug report correct?
    "the symbol F in java.time.DateTimeFormatter is no use in any pattern. It just may cause an exception."

If true, then it seems the compatibility risk would be low since pattern letter "F" as is currently defined is of no use.

Also, the CSR summary needs to be a summary of the action to be taken, that is, changing the pattern definition. The current statement is similar to the problem statement.
