JRockit 1.4.2_03 Linux64 on AS3.0 -Xmx -Xms error!

Question

Hi,
I download the JRockit 1.4.2_03 SDK for Linux(64 bit) from the "http://commerce.bea.com/showallversions.jsp?family=WLJR"
When I run Java with -Xms -Xmx options on AS EL3.0, whatever heap size, the error
messages are thrown out:
Negative or invalid size for maximum heap size - reset to default!
Negative or invalid size for initial heap size - reset to default!
When run on AS2.1, it works.
I don't know why. JRockit 1.4.2_03 doesn't support AS EL3.0?
Thx,
Xuekun

Answer 1

Hmm, that doc page must be a mistake. We are working on getting
NPTL-support on RHEL3.0 into the next service pack of JRockit 1.4.2. I'm
very sorry that the documentation suggests otherwise.
Thanks,

Yes. By setting LD_ASSUME_KERNEL=2.4, it works. But in http://e-docs.bea.com/wljrockit/docs142/intro/newftrs.html,
it says JRockit 1.4.2_03 support NPTL at Red Hat Enterprise Linux 3.
And I just want to test the JVM performance using NPTL.
The command line is very simple. java -Xms1g -Xmx1g

This is a confirmed problem on RHEL3.0 and does not exist on any of the
supported platforms. Note that RHEL3.0 is not on the list of supported
platforms: http://e-docs.bea.com/wljrockit/docs142/certif.html
Running without NPTL (by setting LD_ASSUME_KERNEL=2.4) should work
better, though.
