Description mmortens 1999-10-18 16:22:13 UTC

After upgrading from 6.0 to 6.1 and try to run a java
program I get the error:

/usr/local/Lucent/PMVision# pmvision
Cannot open /proc/05507 for GCCould not create Java VM


pmvision:

jre -cp /usr/local/Lucent/PMVision/pmvision.jar \
-cp /usr/local/Lucent/PMVision/pmvhelp.jar  \
-cp /usr/local/Lucent/PMVision/helpsys.jar  \
-cp /usr/local/Lucent/PMVision/oromatcher.jar \
PMVision $*


When I upgraded to 6.0 I had to switch to using native
threads does this have something to do with it?  Here is my
environment:

I have tried upgrading to jdk1.7v3 with out any change.  Once again
the output is:
# ./pmvision
Cannot open /proc/08420 for GCCould not create Java VM

I am really in a bind any help in resolving this issue is welcome.

Hmm... looks like the JDK is relying on a bug/misfeature
in the older kernel, in that you could read /proc/23 as
/proc/00023. This was fixed in the 2.2.13 (and 2.2.12+fixes
that ships in 6.1).

What JDK are you using? (IBM/Blackdown/etc.)

Comment 4 mmortens 1999-10-22 17:13:59 UTC

I am using blackdown jdk1.1.7v3 and had used v1a

Comment 5 Bill Nottingham 1999-10-22 21:21:59 UTC

You might try using the IBM jdk; it's a jdk bug that it's
trying to access the directory like this.

Comment 6 mmortens 1999-10-25 20:01:59 UTC

I switched to ibm-jdk-l118-linux-x86 and it worked.  The thing that I
don't understand is that it only broke when I upgraded to RH6.1.
Previous to that the Blackdown jdk worked fine for me.  This looks
like it is still a RH problem and would appreciate more info.

Comment 7 Bill Nottingham 1999-10-25 23:07:59 UTC

The kernel changed; it doesn't allow addressing /proc directories
like that any more.
