6.0 2016-07-10 Apache Commons BCEL 6.0 is a major release supporting the new features introduced in Java 6, 7 and 8. It requires Java 7 or higher to run. COMPATIBILITY with 5.2 ====================== Binary compatible - not strictly compatible - The constant interface org.apache.bcel.Constants has been deprecated. Classes which implemented this interface in 5.2 now use the constants defined in the org.apache.bcel.Const class. - The constant interface org.apache.bcel.generic.InstructionConstants has been deprecated. Classes which implemented this interface in 5.2 now use the constants defined in the org.apache.bcel.generic.InstructionConsts class. - Return type of method 'public java.lang.Object getElementAt(int)' in org.apache.bcel.verifier.VerifierFactoryListModel has been changed to java.lang.String. - The BCEL classes do no longer implement java.io.Serializable. Source compatible - Yes, sort of; - The org.apache.bcel.classfile.Visitor interface has been enhanced with additional methods. If you implemented it directly instead of extending the EmptyVisitor class you'll have to implement the new methods. - The org.apache.bcel.generic.Visitor interface has been enhanced with an additional method. If you implemented it directly instead of extending the EmptyVisitor class you'll have to implement the new methods. Semantic compatible - Yes, except: - BCEL 6.0 handles new attributes such as code annotations that could only be processed by implementing a custom AttributeReader in the previous versions. Code relying on this behavior will have to be adjusted since the AttributeReader will no longer be called in these cases. For full information about API changes please see the extended Clirr report: https://commons.apache.org/bcel/clirr-report.html
