    Expression that.formatPattern cannot be unified with expression that.data , because common superclass type java.io.Serializable cannot be passed as an argument to public boolean equals(java.lang.Object)
    Expression that.formatPattern cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression that.data cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Type java.lang.String of variable that.formatPattern does not match with type org.jfree.data.KeyedObjects2D of variable that.data
