No description provided.

Jenkins, this is ok to test.

[srowen]

Is it maybe better still to look for the first line starting with "java version" instead? is that not maybe more explicit?

[fe2s]

Good point! Will change.

LGTM

Nit: str is a built-in function, so using it as a variable name will lead to spurious warnings in some Python linters. I'd just use x or s instead.

Thanks, fixed.
