>
> A StackOverflowError occurs when the PatternScenarioParser parses a very long
> step in a scenario. This happened to us when writing a Given step that
> included a long table parameter.
> This seems to be caused by the well-known regex bug in Java
> (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6337993). The
> patternToPullOutSteps method specifies a pattern that contains an alternative
> wrapped in a star, specifically "(.|\\s)*".
> We were able to use the same strategy as that used to fix JBEHAVE-242.
> One note about the included patch: the test we've added to
> PatternScenarioParserBehaviour, shouldParseStoryWithVeryLongStep, can
> sometimes pass incorrectly depending on the order in which the tests from
> that class are run. If shouldParseLongStoryWithKeywordSplitScenarios runs
> first, our test passes even without the fix applied. We weren't sure what to
> do about this, but on our machine the tests reliably ran in the order in
> which they were defined, so we just kept that one higher up in the file.
> Possibly there are deeper issues to consider here.
