[Viacheslav Kabanovich (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-19720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13068615#comment-13068615 ] 

Viacheslav Kabanovich commented on JBIDE-19720:
-----------------------------------------------

Yes, you are right, in the case of JRE only external libraries are allowed (even if they physically may reside inside the workspace, paths to them should be absolute), so that the check should be just removed from the code.

Still, the confusion remains for referenced libraries that can be selected both from the workspace and from the disk.
