[tomcat-6.0.33] META-INF/context.xml Environment not working

[Tim Watts]

Hello,

My very basic servlet fails to initialize when trying to read its JNDI
environment entry. The app context name is xbasic. The context.xml is in
xbasic.war's META-INF directory and TomCat (6.0.33) correctly copies it
to ${tomcat.home}/conf/Catalina/localhost/xbasic.xml on first deploy.
Below are the relevant snippets. Can anyone see what I'm doing wrong or
is this a bug?

BTW, I'm running this under openjdk 6.
