Description

While parsing large reports, we identified OutOfMemoryError being raised in the surefire-report-parser in case the test file contains large CDATA sections below system-err / system-out in the report.

While this is using a SAX parser, it parses all element contents into a string and that can cause issues for large test reports.
Proposed fix: only keep element contents in memory in case the value is used somewhere for the result.
i.e. system-err / system-out is just discarded.

Sample project which is demonstrating the issue by creating a huge dummy test report and then uses the parser:
