Here's the chain:
The rule for 'super()' constructor calls is that they must appear only as the first line in a constructor. The OP put it in a different place, inside a method, violating the rule stated in the error message:
"Constructor must call super() or this() before return in method CalcFrame1.<init>()V at offset 0"
That's not where the OP's code called 'super()'. Ergo, it violated that rule.
