Reverse engineering strategy cannot be set to custom class if generation target is Hibernate 5.x ------------------------------------------------------------------------------------------------ Key: JBIDE-23149 URL: https://issues.jboss.org/browse/JBIDE-23149 Project: Tools (JBoss Tools) Issue Type: Bug Components: hibernate Affects Versions: 4.4.0.Final Reporter: Antal Varga Assignee: Koen Aers Fix For: 4.4.3.AM1 Attachments: BaseReverseEngineeringStrategy.java, RMAReverseEngineeringStrategy.java The reason for that is the change in ServiceImpl.java in org.jboss.tools.hibernate.runtime.v_5_0*.jar or later. private Object newReverseEngineeringStrategy(String className, Object delegate) {...} tries to load class using the class loader of the delegate object at first which is *org.hibernate.cfg.reveng.OverrideRepository* and resides in *hibernate-tools-x.yy.jar*. The main problem is that while in case of the earlier Hibernate generation targets (e.g. 4.3) the reverse engineering strategy class loading was done by *org.hibernate.util.xpl.ReflectHelper* (and worked well), this option happens only as a fallback case now *BUT this only happens if the constructor has not been found* (only NoSuchMethodException is caught). Therefore a reverse engineering strategy can only be loaded if it is loaded by the classloader of the hibernate-tools-x.yy.jar or one of its parent loaders (OSGI can make the things more complicated). *I think the solution would be to catch ClassNotFoundException as well and try to load reverse engineering class using ReflectHelper in this case.*
