cannot find symbol symbol : constructor JSONTokener(java.io.Reader)

[Mathieu Malaterre <malat@debian.org>]

Does anyone knows why I would be getting:

    [javac] /home/mathieu/debian/collab/deb-maint/jheliosviewer/trunk/jhelioviewer-2.2.1/src/jhv/src/org/helioviewer/jhv/io/DataSources.java:190:
cannot find symbol
    [javac] symbol  : constructor JSONTokener(java.io.Reader)
    [javac] location: class org.json.JSONTokener
    [javac]                 jsonResult = new JSONObject(new
JSONTokener(reader));
    [javac]                                             ^

where:

$ jar tvf /usr/share/java/jabsorb.jar | grep org.json.JSONTokener

Thanks
