Hello,

using Hudson v1.304, Warnings Plugin v 2.8, JDK 1.6.0_13, Tomcat 6.0.18 on a
Windows 2003 Server R2 SP2 (32bit) and I have noticed the following lines in the
stdout.log file:
failed to locate class:
com.thoughtworks.xstream.mapper.CannotResolveClassException:
hudson.plugins.warnings.WarningsResultAction :
hudson.plugins.warnings.WarningsResultAction
hudson home directory: D:\Hudson\.hudson
Exception in thread "Timer-1" java.lang.NullPointerException

the line:
failed to locate class:
com.thoughtworks.xstream.mapper.CannotResolveClassException:
hudson.plugins.warnings.WarningsResultAction

is repeated dozens of times.

many thanks,
andrea
