Subject Bug in propertyset?
Date Thu, 16 Mar 2006 16:53:32 GMT
Hello,

I'm seeing unusual behavior trying to use propertyset.  The build file
is below.  I have a -run target that calls <java> on a class specified
by a property, and several target that set the property and call the
-run target.  I define a propertyset to specify the properties that are
passed to the JVM.  If I attempt "ant -v exhibit-bug", it passes the
correct properties to the forked JVM.  However, if I uncomment the
propertyset lines in run-other (a target that isn't called when running
exhibit-bug), it appears to use the propertyset defined in run-other
rather than the one defined in exhibit-bug.

With the second property set commented out, I get this output:
...
-run:
Executing 'C:\Program Files\Java\jdk1.5.0_05\jre\bin\java.exe' with
arguments:
'-Dbae.ibc.testclient.autologin=true'
'bae.ibc.testclient.BPClientGUI'

With the second property set included (but never called), I get this
output:
...
-run:
Executing 'C:\Program Files\Java\jdk1.5.0_05\jre\bin\java.exe' with
arguments:
'bae.ibc.testclient.BPClientGUI'

Note that bae.ibc.testclient.autologin (which matches the
propertyset/@prefix in exhibit-bug but not in run-other) is not set in
the second call.

Is there some reason it should be working this way?
