WARNING: Content of the region-body on page 2 overflows the available area in block-progression dimension
I am generating a pdf with fop 0.95 version, the problem is that on exception code, I should capture the code, but I am getting the exception described in the title, and the pdf is not generated correctly, page 2 is not showing complete, as it should take steps 4 and 5, and the page looks broken, see the screenshot.
Please check the code where the comment "Exceptions if any" starts, the issue is somewhere there, as when the test fails, that code is called to print in the pdf report, the message and stacktrace of failure, if all tests pass this code is not called and pdf is created correctly.
I already checked these questions, but i am not able to understand what is needed to fix the issue.
Main Page - from here teststepdetails is called, where i think the issue is

Solution
You are limiting the formatter's ability to break across a page because of the many <fo:table-row keep-with-previous="always">.
If you remove some of the keep-with-previous="always", you should get a different result, though I can't tell if that would completely solve your problem.
(And, as @mzjn implies, you might get a different (better) result with the latest FOP version.)
