ActiveMQ violates System Properties
-----------------------------------
Key: GERONIMO-3243
URL: https://issues.apache.org/jira/browse/GERONIMO-3243
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: ActiveMQ
Affects Versions: 2.0-M3, 1.2, 2.0-M4
Reporter: solprovider
The latest Geronimo 1.2 and 2.0 use ActiveMQ. (Would someone familiar with
Geronimo development please add all affected versions?)
ActiveMQ adds a HashMap as a global Property named
"org.apache.activeio.journal.active.lockMap".
Properties must use Strings for keys and values per
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Properties.html
This causes any code reading all the Properties and expecting Strings to error.
The error can be produced with Cocoon's SitemapVariableHolder for XMAP
constants:
<map:component-configurations><global-variables>
<myConstant>Hello World</myConstant>
</global-variables></map:component-configurations>
"{global:myConstant}" errors
The permanent fix is for Geronimo to update to a better version of ActiveMQ,
either downgrading to before the bug was programmed or wait for the ActiveMQ
team to follow the standards. That is unlikely to be tested and released
quickly.
The quick fix is to disable the offensive code. For Geronimo 1.2 on Windows,
add this line at the beginning of STARTUP.BAT:
SET GERONIMO_OPTS=-Dorg.apache.activeio.journal.active.DisableLocking=true
%GERONIMO_OPTS%
David Jencks suggested that Geronimo can set the
org.apache.activeio.journal.active.DisableLocking property in a Geronimo
SystemProperties gbean, there's one called ServerSystemProperties in
j2ee-server.
