I'm not able to duplicate this problem with the steps provided.   Since there doesn't seem to be an indication that projects aren't working with "Serve modules without publishing" enabled, I'll assume it is working given this NPE occurs.  With "Serve modules without publishing" enabled, no <Context> should have a docBase pointing to the ".../tmp0/wtpwebapps" folder.  This log output suggests that somehow, a <Context> in the server.xml found under the Servers project in your workspace got "disconnected" from it's associated project.  As a result, it's seen as an "external" <Context> and is not be adjusted for "Serve modules without publishing".  As long as this "disconnected" <Context> is present, you will get this error.  Manually removing it should get rid of the error.

The question is how the brick_spot_sys project got "disconnected".  If the NPE is still occurring, please attach the server.xml found under the Servers project in your workspace.  Also, does the  brick_spot_sys project still exist in your workspace?

It seems WTP 3.2.1.v201007151559 has resolved this problem. I've updated and it works well.
