Found the fix.
Noticed that we have already opened bug tickets in ActiveMQ concerning this.
*ISSUE:*
It's not directly related to ActiveMQ, it's due to an upgrade of Jetty
which has some fixes that restrict the symbolic reference usage. (
/opt/app-1 -> /opt/app)
*FIX:*
Referring to actual reference (/opt/app-1) instead of symbolic reference
(/opt/app) will also fix the issue. Instead, there is a way to fix this
issue in jetty.xml
...<bean class="org.eclipse.jetty.webapp.WebAppContext">
<property name="contextPath" value="/admin" />
<property name="resourceBase" value="${activemq.home}/webapps/admin" />
<property name="logUrlOnStart" value="true" />
<!-- add here. start -->
<property name="aliasChecks">
<list>
<bean
class="org.eclipse.jetty.server.handler.ContextHandler$ApproveAliases"/>
</list>
</property><!-- end --></bean>
