When using eclipse path properties in source path in New Server wizard for a new OpenShift 3 server adapter, validation does not work properly. E.g. I choose a workspace project by browsing workspace and choosing it, it fill into the text widget for source path

${workspace_loc:/org.jboss.tools.openshift.ui.bot.test}

and it is OK, next button is enabled. But if I cut/paste it there again or if I type workspace location manually, not via browsing workspace project, it is validated as incorrect path and it is not possible to proceed through wizard.
