Then target is to compare new lib version to API described in XML. project site: http://pyx4me.com/snapshot/jour/signature.html This is what causing the problem: CtField field = new CtField(CtClass.longType, "test", klass); CtField.Initializer initializer = CtField.Initializer.constant(1); klass.addField(field, initializer); // Then later when Object value = field.getConstantValue(); //value is always null and can't be used for comparison. when I call klass.writeFile(); The .class is created correctly and when decompiled I see that int filed is properly initialized . BUT When javassist loads again the generated classes field.getConstantValue(); still null! was: I'm creating tool to verify Java API compatibility I'm converting class files to XML and then XML to classes creating CtClass objects that have empty implementation.

[ http://jira.jboss.com/jira/browse/JASSIST-37?page=all ] Vlad Skarzhevskyy updated JASSIST-37: ------------------------------------- Workaround Description: The problem was field.setModifiers() was not called before klass.addField(field, initializer); So initializer was not suppose to be created. Later filed was modified to static final.
