-

I didn't try the latest builds, I am speaking about 2.1.6. In my setup the 
error is raised even if there are no spaces in 

* the tomcat installation path : /opt/tomcat/apache-tomcat-5.5.27
* the webapplication context path: 
/opt/tomcat/apache-tomcat-5.5.27/webapps/voms#test_vo_mysql

So it could be that the presence of spaces isn't the only reason behind this 
bug.

-

I still have to try with the latest--but just to add:

It's not *just* the Tomcat install directory--it's the app deploy directory. 
Under IntelliJ, for example, if I have a run config that creates an exploded 
app in a directory w/ spaces the error also happens, even though my Tomcat 
install itself isn't on a path with spaces. Same issue, but can get there in 
different ways.

Setting my webapp to devMode with struts 2.1.6 causes the same error, even if 
the path leading to my tomcat installation contains no spaces.

Did you try to use latest Struts2 build [1] or Xwork build [2]?

[jira] Commented: (WW-2956) setting devMode value to true causes NullPointerException

Musachy Barroso commented on WW-2956:
-

The try/catch part is good, but I think the check for null should stay in 
place, as long as there is a constructor of FileRevision that doesn't take a 
file parameter. For example, if the file cannot be read, then file will be 
set to null, in that method, and the NPE will be triggered. Trying to think 
outside the box, why keep track of a file that can never be reloaded anyway? 
If the file cannot be read, or it does not exists, we should not add it to the 
map at all.
