Subject [jira] Commented: (HARMONY-6101) [classlib][luni] Extraneous path separator in *.boot.class.path on IBM VME 5
Date Thu, 26 Feb 2009 12:45:02 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-6101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12676979#action_12676979

Jim Yu commented on HARMONY-6101:
---------------------------------

Hi Pavel,
Sorry for the misprint, I've updated my patch. Since this work around only adds a check, it
will not affect the usage of current VM.
I think it can be filed at any appropriate time. 

For your concerns:
If there are double separators contained in the boot class path, provided by a VM, it is definitely
a VM defect. Currently,
the double separators were not introduced by the VME 5 alone. It resulted from the VM added
one separator at the end 
of the root class path, provided by itself, and classlib added one simultaneously at the start
of the boot class path retrieved 
from properties. So I think we just need to check whether  there is a separator at the end
of the root class path, provided by VM.

> By using IBM VME 5, while running SystemTest.test_getProperty_bootClassPath test case
on 
> both Linux and Windows, there is a failure:
> Boot class path contains extra patch separator.
> In the boot class path, I can see an extra ':' on Linux after:
> deploy/jdk/jre/bin/default/security-kernel.jar
> Since similar issue has been resolved in HARMONY-3298 and the test can pass on IBM VME
4.
>  I suppose this may be caused by the VME 5. After my further investigation, I found out
that the root
>  cause of this issue is a behavior change by VME 5. For VME 4, there is no CP separator
at the end
>  of the boot strap class path set by VM. So it is OK for Harmony to extend the boot class
path with 
> values retrieved from bootclasspath.properties begins with a CP separator . But for VME
5, root class
>  path set by VM will add a CP separator at the end, so an repeated CP separator is generated.
Though 
> it was caused by the change of VME, I find out a tricky method to make Harmony work well
on both 
> VME 4 and VME 5. I've tested my patch. It works fine on VME4, VME5 and DRLVM.
> Can someone take a look at this? Thanks.
