It has become quite common to use the following code

.rows((int) INSTRUCTIONS.lines().count() + 1)

to set the number of rows for PassFailJFrame. Yet the `String.lines` method is not available in Java 8.

During backport process, this code was replaced with
        INSTRUCTIONS.split("\n").length
which is correct.

Other tests use
        INSTRUCTIONS.length()/45
which will produce the wrong number and the instruction text will not fit.


After JDK-8340308 is backported to Java 8, these usages can be removed completely, as the PassFailJFrame framework will provide the expected default. If required, the number of rows can be adjusted by using the `rowsAdd` method.
