#613 Report generation crashes due to 0x0 in CDATA

[Dave Grove]

Tail of verbose.log from rvmx86lnx64 run from last night.

Report generation is crashing because it is finding an 0x0 in the CDATA section. Not sure if the root cause is the injection of the 0x0 or inability to process it, but this is why the email didn't go out last night (and probably the night before).

The inability of the xslt engine to deal with an 0x0 is the problem but it is curious that this character is not generated on other platforms. Could you either attach or send me off list the Results.xml that caused the above.

Looking at the old testing framework it specifically removed 0x0s so it looks like this problem is not new but I would prefer that it was fixed rather than being silently ignored.

My vauge recollection is that jBYTEmark maybe have 0x0 in it's output?

Sorry I can't give you that log since the nightly run has started already, but I suspect it's reproducible so it should be in ~regression/night-sanity on rvmx86lnx64 within a few hours.

The results should be archived in ${results.dir}/archive directory under 20070226.xml.gz (or something similar) so if you can pass that on I can identify exactly which test produced it.

ok. Steve or Robin, could one of you change the version of jBYTEmark in /usr/share on the regression machines as suggested by Peter. This is a high priority item since until we fix this the mightly-runs on rvmx86lnx64 aren't being archived or reported. Thanks,

Peter's patched version is now in /usr/share/benchmarks on rvmx86lnx64, other machines to follow Real Soon Now.

Fixed on rvmx86lnx64 - assumed the fix has propagated to other machines.
