Understood, but thanks for making it clear. I always prefer the 'cock-up' theory to the 'conspiracy' theory for such things ;-) I can't see the Sun-based code delivered in IBM 1.5, so had to go through other people who can to get some answers. Here's what I found out, slightly reformatted from your original listing: == sun 1.5 vs. ibm1.5 == java.awt.peer: Method java.awt.peer.WindowPeer.updateFocusableWindowState() is missing in IBM1.5 The claim is that this method doesn't exist in Sun code either (as I said above, I can't check directly). This package isn't listed in the JSE5.0 javadoc. javax.xml.datatype: Field javax.xml.datatype.DatatypeFactory.DATATYPEFACTORY_IMPLEMENTATION_CLASS has value “com.sun.org.apache.xerces.internal.jaxp.datatype.DatatypeFactoryImpl” in Sun1.5, but value “org.apache.xerces.jaxp.datatype.DatatypeFactoryImpl” in IBM1.5 This is deliberate, since IBM doesn't do the 'com.sun' package renaming, so this field has the name of the actual type that is to be used as the factory impl. org.omg.stub.javax.management.remote.rmi: Class org.omg.stub.javax.management.remote.rmi._RMIConnectionImpl_Tie missing in IBM1.5 Class org.omg.stub.javax.management.remote.rmi._RMIServerImpl_Tie missing in IBM1.5 This package is not part of the JSE API (but the inconsistency is being checked). org.w3c.dom.html: method org.w3c.dom.html.HTMLFrameElement.getContentDocument() missing in IBM1.5 method org.w3c.dom.html.HTMLIFrameElement.getContentDocument() missing in IBM1.5 method org.w3c.dom.html.HTMLObjectElement.getContentDocument(): missing in IBM1.5 method org.w3c.dom.html.HTMLOptionElement.setSelected(boolean): missing in IBM1.5 This package is also not part of the JSE API (but the inconsistency is being checked). - o - == ibm1.5 vs. sun1.5 == java.lang: method java.lang.StringBuilder.append(java.lang.StringBuilder): missing in Sun1.5 This is a bug in the IBM impl. you can expect that method to disappear. javax.management.remote.rmi: Class javax.management.remote.rmi._RMIConnectionImpl_Tie missing in Sun1.5 Class javax.management.remote.rmi._RMIServerImpl_Tie missing in Sun1.5 This also looks like a bug in the IBM impl (and looking at how the type names match those listed above as missing in org.omg.stub... it looks to me like the Ties were somehow created in the wrong package). javax.xml.datatype: Field javax.xml.datatype.DatatypeFactory.DATATYPEFACTORY_IMPLEMENTATION_CLASS has value "org.apache.xerces.jaxp.datatype.DatatypeFactoryImpl” in IBM1.5, but value “com.sun.org.apache.xerces.internal.jaxp.datatype.DatatypeFactoryImpl” in Sun1.5 This is the same String const case as listed above. ... and the remainder of these are non-JSE-API packages. Again, the difference is being checked. org.omg.stub.java.lang: Package org.omg.stub.java.lang: missing in Sun1.5 org.omg.stub.java.security: Package org.omg.stub.java.security: missing in Sun1.5 org.omg.stub.java.util: Package org.omg.stub.java.util: missing in Sun1.5 org.w3c.dom.html: Method org.w3c.dom.html.HTMLOptionElement.setIndex(int) missing in Sun1.5 Method org.w3c.dom.html.HTMLTableCellElement.setCellIndex(int) missing in Sun1.5 Method org.w3c.dom.html.HTMLTableRowElement.setCells(org.w3c.dom.html.HTMLCollection) missing in Sun1.5 Method org.w3c.dom.html.HTMLTableRowElement.setRowIndex(int) missing in Sun1.5 Method org.w3c.dom.html.HTMLTableRowElement.setSectionRowIndex(int) missing in Sun1.5 org.w3c.dom.xpath: Package org.w3c.dom.xpath: missing in Sun1.5 - o - Thanks again for pointing these out. Of course, the IBM Java SDKs all pass the JCK, so it may be that we require additional signature tests to catch some of these.
