[cdt-dev] CDT test command line and cron

["Alex Yin" <alex_yin88@xxxxxxxxxxx>]

Hi,

Below is an email sent to "cdt-test-dev" mailing list. I am copying it here 
to try to get more feedbacks, sorry for the duplicate.
--------------------------------------------------
I have been trying to run CDT regression tests from the command line on a 
Linux machine using Eclipse 3.1 and CDT 3.0.0, and got some strange issue. I 
have a shell script, which calls "java -cp <eclipse_home>/startup.jar ...". 
If this script runs from a console/terminal under X-Windows, it works fine; 
but if it runs from a cron job, following error message comes up after "java 
-cp <eclipse_home>/startup.jar ...":

eclipse-test:

I googled this error message, and found following bug report, which is very 
similar to what I have seen:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=106396

The suggestion there is to set "JAVA_HIGH_ZIPFDS" to 500 or higher. So 500, 
1000, and 1500 were tried, but none worked. I have also compared all the env 
variables between cron environment and xterm environment, and made sure they 
are the same, but still get the same error. One thing hasn't been tried is 
to use a different Java virtual machine, will that help? Is there any 
solution or workaround for this problem?

Thanks,
--alex
