Relative private-asset throws exception

           Summary: Relative private-asset throws exception
           Product: Tapestry
           Version: 3.0
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: Framework
        AssignedTo: tapestry-dev@jakarta.apache.org
        ReportedBy: davide.orlandi.due@synago.it


--- test.application: ---

<application engine-class="org.apache.tapestry.engine.BaseEngine" name="test">
    <page name="Home" specification-path="classes/testpackage/Home.page"/>
</application>

--- classes/testpackage/Home.page: ---

<page-specification class="org.apache.tapestry.html.BasePage">
    <private-asset name="testasset" resource-path="icon.gif" />
</page-specification>


--- The app throws the following exception: ---

org.apache.tapestry.ApplicationRuntimeException
Unable to instantiate component Home: null
component: org.apache.tapestry.html.BasePage@44ac5e[Home]
location: context:/WEB-INF/classes/testpackage/Home.page, line 6, column 63

"icon.gif" is not missing or misspelled (I get a different error if I rename 
it).
I noticed the problem first when using a package directory, but moving 
Home.page, Home.html and icon.gif out of the package into the context root 
doesn't change it.

Test setup is Tomcat 5.0.18, but I remember it happening with 4.x too.

An absolute private-asset (resource-path="/testpackage/icon.gif") works, so 
this is not a great problem anyway.


(I hope I'm not missing something obvious; if so please forgive me).
