Results for this aren't available publicly yet. I simply downloaded japitools myself last night, and ran a comparison between JDK 1.5 and current Classpath CVS HEAD, which is where I obtained the quoted figure. Primarily, I just wanted to see if it worked; as there are very limited byte-code changes (the language changes are all done at the compiler and library level), I had a feeling it would and was proved correct. The published JAPI results (http://www.kaffe.org/~stuart/japi/) still only go up to 1.4, and do appear to need updated (last Classpath scan was 26/12/2004). It would be great to see 1.5 comparisons added for both Classpath HEAD and the new generics branch (which should hopefully be in sync in a few minutes). I did get a few errors when japizing 1.5, but these don't appear to be related to 1.5 changes (they don't appear to use any of these features, while branches such as java.util and java.lang which have major changes scan fine). Stuart or someone else may want to look into this, the following all throw NullPointerExceptions: javax.management.MBeanAttributeInfo: java.lang.NullPointerException javax.management.Notification: java.lang.NullPointerException javax.management.ObjectName: java.lang.NullPointerException javax.management.modelmbean.InvalidTargetObjectTypeException: java.lang.NullPointerException javax.management.modelmbean.ModelMBeanAttributeInfo: java.lang.NullPointerException javax.management.modelmbean.ModelMBeanConstructorInfo: java.lang.NullPointerException javax.management.modelmbean.ModelMBeanInfoSupport: java.lang.NullPointerException javax.management.modelmbean.ModelMBeanNotificationInfo: java.lang.NullPointerException javax.management.modelmbean.ModelMBeanOperationInfo: java.lang.NullPointerException Japize javax.management.modelmbean.XMLParseException: java.lang.NullPointerException Japize javax.management.relation.MBeanServerNotificationFilter: java.lang.NullPointerException Japize javax.management.relation.RelationNotification: java.lang.NullPointerException Japize javax.management.relation.RelationTypeSupport: java.lang.NullPointerException javax.management.relation.Role: java.lang.NullPointerException Japize javax.management.relation.RoleInfo: java.lang.NullPointerException Japize javax.management.relation.RoleResult: java.lang.NullPointerException Japize javax.management.relation.RoleUnresolved: java.lang.NullPointerException Japize javax.security.auth.kerberos.KerberosKey: java.lang.NullPointerException These don't affect our percentage score, as GNU Classpath doesn't implement these packages at this point anyway. The management errors seem particularly odd, as JMX existed outside the JDK prior to 1.5. I guess they just hit some obscure japitools bug. -- Andrew :-) Please avoid sending me Microsoft Office (e.g. Word, PowerPoint) attachments.
