Installed MyEclispe, plugin verison into this Eclipse, got duplicate errors. Did Eclipse - clean - got Null ptr exceptions when strarting up. Maybe the only way to use MyEclipse & JBoss Tools is by using a 2nd instance of Eclipse for MyEclipse, if there is value in doing this. Using Eclipse 3.3.1, MyEclipse 6.0.1, JBoss Tools 2.0.0 GA View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4118016#...
