NPE in JavaComponentContext
---------------------------
Key: GERONIMO-2666
URL: http://issues.apache.org/jira/browse/GERONIMO-2666
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Affects Versions: 1.2, 2.0-M1
Environment: All
Reporter: Anita Kulshreshtha
Priority: Minor
Examining attributes of
j2eeType=JavaComponentContext,ServiceModule=rmi-naming/... using Jconsole gives
NPE. The environment attribute is shown as {} in JMXViewer. To reproduce this
start Geronimo (I used tomcat-j2ee) in jdk1.5 and run jconsole. Examine the
attributes using:
geronimo --> o.a.g.configs/rmi-naming/... --> JavaCompContext --> Context
