Hi!, I´ve been struggling for some time to get the JBoss AS 4.0.5GA to work in debug mode using the JRockit VM. The main problem I am facing is that the breakpoints (setted on EJBs) are sometimes not hitted , and when they are, once the method in which they were setted finishes, the CPU utilization climbs to 100% and the AS hangs. Development environment: + JBoss 4.0.5GA along with EJB3.0, JSF and JPA (Default Hibernate implementation). + JRockit 1.5.0 R27.4.0 + Netbeans 5.5.1. Any clues will be much appreciated.
