Hi,
As per documentation, most of the concrete implementations of the Configuration interface are not thread-safe when modifications are involved. However, looking at AbstractFileConfiguration ( http://svn.apache.org/repos/asf/commons/proper/configuration/trunk/src/java/org/apache/commons/configuration/AbstractFileConfiguration.java ) and (http://svn.apache.org/repos/asf/commons/proper/configuration/trunk/src/java/org/apache/commons/configuration/AbstractHierarchicalFileConfiguration.java) , it appears that access *is* synchronized through a reload lock. Do the concrete implementations (e.g XMLConfiguration) do something that makes them non thread-safe with respect to reloads? thanks, -Sidharta S
