more or less a duplicate of issue 240445, not sure what we can do here. 137M sized text is pulled from the surefire report file via saxparser. No matter what parser we use (a pull kind comes to mind), we would eventually have to store that (and other) strings in the test results window anyway. maybe just take some precautions and if the report file is huge, refuse to show it in test results window? or via pull parser manage to cut the output to manageable size? Any idea Fanis? have you encountered this with ant projects?

AFAICR there was not a similar issue for ant. Anyway 100+MB test results report seems rare. A change in the parsing algorithm is out of scope for 8.0 I am afraid. At this point I can eliminate further processing of the results file if it bigger than say 50MB. Would that be acceptable?

Would that be acceptable? sounds reasonable, but doesn't prevent a OOME from multiple below 50M report files. a pull parsing solution would allow us to process such files but only include output/texts with a given maximum size. (well in the kilo area not mega)

(well in the kilo area not > mega) I agree but at least the fix minimises the risk of the OOME since AFAIK max heap size is set ~25% of available ram by default. I filed an enhancement to keep track of this and to be fixed in next release. Thank you
