Critical Description
I am experiencing a NPE when starting a NAS application in our qualification environment. It runs a 64bits JDK 1.6.0 :
[dlweb@acker conf]$ java -version
java version "1.6.0_32"
Java(TM) SE Runtime Environment (build 1.6.0_32-b05)
Java HotSpot(TM) 64-Bit Server VM (build 20.7-b02, mixed mode)
I can't reproduce this bug on my dev setup, that runs JDK 1.6.0_16.
[dlweb@menelas1 log]$ java -version
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)
Here's the stacktrace:
