jtreg: how to set maxOutputSize?

[roger riggs]

jtreg /jtharness is limiting the output size for some test runs.

I see a documented setting for javatest.maxOutputSize but it does not 
seem to change the behavior.
Invoked as:

$JTREG_HOME/linux/bin/jtreg  -Djavatest.maxOutputSize=1000000 
-jdk:$JAVA_HOME -dir:$WS/jdk/test/ $*

Any suggestions?

Thanks, Roger
