[Soot-list] can't get npcolorer to work on eclipse

[Venkatesh Vinayakarao]

*What works?*

Am able to use jap.npcolorer through command-line. The xml attributes are
generated properly. I use the following command:

java -cp
sootclasses-2.5.0.jar;jasminclasses-2.5.0.jar;polyglotclasses-1.3.5.jar
 soot.Main -cp C:\Progra~1\Java\jre7\lib\rt.jar;./input; -output-dir
C:\tools\soot\output  -process-dir C:\tools\soot\input  -xml-attributes -f
J -p jap.npcolorer on NullPointer

*What does not work?*

Am trying to reproduce the same through eclipse (soot 2.5.2 is installed).
Steps: Right click on source file -> soot -> process source file -> run
soot. In the dialog, I selected output format as Jimple and phase
options/jap/null pointer colourer/enabled.

Note that I have already added the jars to buildpath.

When I run soot, I get NullPointerException with the following stacktrace:

What am I doing wrong?

To my limited knowledge, java.lang.CharSequence should be picked up from
rt.jar and eclipse should automatically take care of that. I see rt.jar in
the command's cp (pasted above). Not sure what else is missing.

Thanks,
Venkatesh.
