[jbosstools-dev] [HELP NEEDED] Java 9 and jbosstools-hibernate

Hi it's a long time i'm trying to make jbosstools-hibernate work with Java. The main problem is the class loader: https://github.com/jbosstools/jbosstools-hibernate/blob/b3826209cae7327a9... . *sub-problem #1 (getResource) method *(solved) If you google how to load resources in Java 9, then you find that now you should do *classloader.getUnnamedModule().getResourceAsStream()* instead of previous *classloader**.getResourceAsStream(). *But we want, that our code could be built inside Java 7 Execution Environment (see MANIFEST.MF). So what i did for the *getResource <https://github.com/jbosstools/jbosstools-hibernate/blob/b3826209cae7327a9... method. If we have null for *super.getResource(name)*, then i manually search for resources next to hibernate.cfg.xml using java.nio.file.Files.walkFileTree. And it works! It needs to be polished a little bit, but anyway it solves the problem. *sub-problem #2 (findClass)* method (HELP NEEDED) After the resource is found (and in hibernate usually it's a mapping xml file) using the solution above, we try to associate it with the class and load it with the classloader. However, the current *classloader.findClass <https://github.com/jbosstools/jbosstools-hibernate/blob/b3826209cae7327a9... doesn't find anything (ClassNotFoundException). I tried to *HibernatePlugin.getDefault().getBundle().loadClass(name)*, because i found that this loading classes stuff is fixed in core Eclipse and bundles must load classes without problems, but it doesn't work either. So my main questions are: 1) This code is rather old, and i suppose that it must be refactored in general. If you have any thoughts of how to do it better, i'd be glad if you share them :) 2) How to load user classes correctly now in Java 9 in Eclipse? 3) Maybe the better way is to create a plugin/feature with a minimal Execution Environment set to Java 9, which will be activated only when java 9 is used and implement such things like *classloader.getUnnamedModule().getResourceAsStream() *there? And switching between them using extension points mechanism. Is it possible? Does it worth it? If yes, then it'll require quite big work, in my opinion. Looking forward to any help. Thanks in advance! Bocharov Dmitrii
