lichtin opened a new issue, #2119:
URL: https://github.com/apache/activemq/issues/2119
ActiveMQ (6.2.6 in this case) does not start if there is no Internet access.
This seems due to a missing entry in the "META-INF/spring.schemas" file.
Upon adding the following line
http\://www.springframework.org/schema/beans/spring-beans.xsd=org/springframework/beans/factory/xml/spring-beans.xsd
then ActiveMQ is able to start without reaching out to the Internet.
