hello! i have a similar problem. Exception in thread "main" java.lang.NullPointerException: Cannot invoke "org.jd.core.v1.model.classfile.ClassFile.getAccessFlags()" because "classFile" is null at org.jd.core.v1.service.converter.classfiletojavasyntax.processor.ConvertClassFileProcessor.process(ConvertClassFileProcessor.java:63)

Have you solved the problem yet?
