• OS: Linux
• Database: N/A

Problem Description

An error is logged if GlassFish is started with a virtual server in state "off". The error valve is not loaded, which is not an issue for a virtual server which is turned off. Only a nasty error in the log:

Couldnt load specified error report valve class: {0}
java.lang.NullPointerException

Steps to reproduce

1. Start GlassFish domain1 with the default configuration
2. Set the virtual server "server" to state "off"
3. Stop GlassFsih server
4. Start GlassFish server - the error is logged

The reason is that the server context is not set when the setIsOff method is called in WebContainer.createHost(). The context is a couple of lines later in WebContainer.createHost.

Impact of Issue

No real impact. Only a nasty error in the log, which looks like a serious issue but could be ignored.
