[jira] [Commented] (LANG-1701) Where is the difference?
[ https://issues.apache.org/jira/browse/LANG-1701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17742043#comment-17742043 ]
Gilles Sadowski commented on LANG-1701:
---------------------------------------
To ensure that no (de)serialization issue, due to the particular (binary) format at hand, is involved in this weird (?) behaviour, I saved the 2 loaded objects to XML (using [{{XMLEncoder}}|https://docs.oracle.com/javase/8/docs/api/java/beans/XMLEncoder.html] from the JDK): The XML outputs (from the two object being compared) show no differences.
Do you agree that this confirms that the [Lang]'s [{{ReflectionDiffBuilder}}|https://commons.apache.org/proper/commons-lang/javadocs/api-release/org/apache/commons/lang3/builder/ReflectionDiffBuilder.html] is buggy, or has major (undocumented) limitations?
