I'm working with JAXB's xjc tool to generate Java classes from an AUTOSAR XSD file and encountered an IllegalArgumentException indicating an illegal class inheritance loop. Here's the error message I received:
Exception in thread "main" java.lang.IllegalArgumentException: Illegal class inheritance loop. Outer class TargetIPduRefElement may not subclass from inner class: TargetIPduRefElement at com.sun.tools.xjc@4.0.3/com.sun.codemodel.JDefinedClass._extends(JDefinedClass.java:247) at com.sun.tools.xjc@4.0.3/com.sun.tools.xjc.generator.bean.ImplStructureStrategy$1._extends(ImplStructureStrategy.java:96) at com.sun.tools.xjc@4.0.3/com.sun.tools.xjc.generator.bean.BeanGenerator.<init>(BeanGenerator.java:187) at com.sun.tools.xjc@4.0.3/com.sun.tools.xjc.generator.bean.BeanGenerator.generate(BeanGenerator.java:141) at com.sun.tools.xjc@4.0.3/com.sun.tools.xjc.model.Model.generateCode(Model.java:259) at com.sun.tools.xjc@4.0.3/com.sun.tools.xjc.Driver.run(Driver.java:365) at com.sun.tools.xjc@4.0.3/com.sun.tools.xjc.Driver.run(Driver.java:198) at com.sun.tools.xjc@4.0.3/com.sun.tools.xjc.Driver._main(Driver.java:117) at com.sun.tools.xjc@4.0.3/com.sun.tools.xjc.Driver$1.run(Driver.java:76)Has anyone encountered a similar issue and found a way to resolve it? I'd appreciate any insights or suggestions on how to debug this problem.
