Kaha Store puts a non-string into System properties
---------------------------------------------------
Key: AMQ-1254
URL: https://issues.apache.org/activemq/browse/AMQ-1254
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 4.1.2
Reporter: David Jencks
Attachments: Kaha-Store.patch
KahaStore puts a hashmap into SystemProperties, which causes problems with
programs that expect only strings as properties. In particular some versions
of Hibernate assume all system properties are strings: this is causing
difficulties running roller in geronimo 2.0
Attached is a proposed solution. I have no idea how to test it. I get the
same 7 failures and one error building amq with and without the change.
The proposal stores the list of locked directories in a string and converts it
back and forth to a map whenever it is accessed. I use a constant string as
the vm-wide lock monitor formerly provided by the HashSet. According to the
String javadoc constant strings are intern()ed and the same instance is
provided in any classloader: this makes it suitable for a vm-wide lock monitor.
