Description

Commented-out lines that end in a semicolon cause an error.

For example:

/*

describe keyspaces;

*/

 

This produces an error:

SyntaxException: line 2:22 no viable alternative at input '<EOF> (...*
describe keyspaces;...)

 

It works as expected if you use syntax:

– describe keyspaces;

 

Environment:

python:3.7.7-slim-stretch (docker image)

 

I found that this was first seen here, and was patched, but the bug appears to have resurfaced:
