* Fix ColumnSignature error message and jdk17 test issue. On jdk17, the "problem" part of the error message could change from NullPointerException to: Cannot invoke "String.length()" because "s" is null Due to the new more-helpful NPEs in Java 17. This broke the expectation and led to test failures on this case. This patch fixes the problem by improving the error message so it isn't a generic NullPointerException. * Fix format.
