jtreg: handle StringIndexOutOfBoundsException when parsing summary.txt

Handle a case where a badly formatted summary.txt causes a
StringIndexOutOfBoundsException to be generated. This can happen when
the format in the summary.txt file has additional lines of output from
a failed test.

A real-world example is as follows:
