[jbosstools-issues] [JBoss JIRA] (JBIDE-12050) Unable to Run Browsersim

[Yahor Radtsevich (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-12050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12697262#comment-12697262 ] 

Yahor Radtsevich commented on JBIDE-12050:
------------------------------------------

The reason of this exception is that loader of BrowserSim adds all fragments of {{org.eclipse.swt}} to the classpath.

{{org.jboss.tools.xulrunner.initializer}} is one of these fragments. It is a part of VPE and that is why its signature does not match signature of {{org.eclipse.swt}} plugin.

Actually, BrowserSim needs only {{org.eclipse.swt.platform_id}} fragment (where platform_id={win32.win32.x86 or gtk.linux.x86, etc.}). {{org.jboss.tools.xulrunner.initializer}} and similar fragments are not needed.
