Hello, Our company is currently using Xalan 2.6. However, we have found that there is a memory leak in the XMLReaderManager class, when the XMLReader instances are not properly removed after the thread finishes and is garbage collected. This issue has been known and is now fixed in Xalan 2.7.0. Therefore, we are now analyzing whether it is suitable for us to migrate to Xalan 2.7.0. The problem that arrises is that we do not know if there are any backward compatibility issues between 2.7.0 and 2.6. After spending some time reading the release notes I have found the following changes that might affect the migration (confirm with Yes / No if these are important changes )
1.The behavior of the default ErrorListener was changed in this release of Xalan-Java, in order to conform with a clarification of the required behavior described by JAXP 1.3 ...The default ErrorListener of the old Xalan-Java Interpretive processor throws exceptions on errors and fatal errors. If your code expects exceptions to be thrown on errors and fatal errors, you have to set a customized ErrorListener on TransformerFactory and/or Transformer. -* Assuming that we do what is described here, is there any other parts of the code Xalan code affected by this behaviour ? * 2. In this release of Xalan-Java the code related to serialization of output result trees has been pulled out of xalan.jar and moved into a new jar file, named serializer.jar.Although the code has been modified to create a stand-alone jar, the serializer public APIs have not changed and the package names and classnames are the same as they were last release. *- From what I understand, there are no consequences besides adding and additional .jar file to the build path. Is that correct ? *3. Are there any additional major changes from 2.6 to 2.7.0 that need to be addressed? 4. *Is there a list, containing all the bug-fixes with the appropriate method / class signature and attribute changes? I saw the history.html file - is this the complete list?* Thank you in advance. Warm Regards, Dragomir Stanchev
