Warning

Icon

This release has been retracted due to bug AMQ-3491. It is no longer downloadable from ASF servers. Please use the ActiveMQ 5.4.3 Release instead.

Apache ActiveMQ 5.4.0 is primarily a maintenance release which resolves 283 issues.

New Features in 5.4.1

New Features in 5.4

Note: XML configuration is now validated against the schema

Icon

The XML configuration syntax is now validated. The broker schema element is an alphabetically ordered sequence. Validation can now cause existing xml configuration files, with out of order elements, to fail to load with XML parse errors, halting the broker start. Fix any ordering issues to continue.

Note: New jetty XML configuration

Icon

The jetty XML configuration now uses direct jetty bean syntax in the absence of xbean support. This renders existing (pre 5.4) jetty xml configuration invalid. It will be necessary to reapply custom changes using the default jetty.xml as a template.
