XML Editor broken in Eclipse 2020-03 ? -------------------------------------- Key: JBIDE-27160 URL: https://issues.redhat.com/browse/JBIDE-27160 Project: Tools (JBoss Tools) Issue Type: Bug Components: xml-structured-editor Affects Versions: 4.14.0.Final Reporter: Thomas Kernstock Priority: Major Fix For: 4.15.0.Final Hi Guys, I hope this is the right place to post this issue. I Upgraded to eclipse 2030-03 and installed JBoss Tools from the marketplace - version 4.14.0, using the CDI, Deltaspike, JSF and Webpageeditor. I'm running eclipse on Windows 10 under Oracle JDK 8. After createing a fresh workspace and a new CDI Project, i'm not able to open any xml file with the JBoss XML Editor. In the errorlog I find the following stack trace: org.eclipse.swt.SWTError: Cannot initialize Drop at org.eclipse.swt.dnd.DND.error(DND.java:281) at org.eclipse.swt.dnd.DND.error(DND.java:241) at
