[jira] Commented: (HARMONY-6072) [buildtest][eut][drlvm] Remove duplicate entry for classlib of Harmony

["Pavel Pervov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-6072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12663325#action_12663325 ] 

Pavel Pervov commented on HARMONY-6072:
---------------------------------------

Look in classloader.cpp: bootstrap_components_classpath and get_kernel_path both return gc_gen.jar as the path element. The first is from harmonyvm.properties, the second - from helper registry.

Then this path is set as vm.boot.class.path and sun.boot.class.path. It looks like Eclipse is using one of these.

There is duplication check in SetBCPElement but that is invoked after setting these properties.

The idea of the fix is to reconstruct boot class path string after the call to SetClasspathFromString(vmboot), and move setting vm.boot.class.path and sun.boot.class.path after that with new reconstructed value.

Moreover, it looks like DRLVM has the bug that dependent jars referenced from jar manifests on boot class path are not referenced by vm.boot.class.path and sun.boot.class.path properties, as these properties are set before jar manifests are extracted.

Should we file separate JIRA on this or fix it along with this issue?
