> 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.*
