    39Expression e.printStackTrace() cannot be parameterized, because it has dependencies to/from statements that will be extracted
    40Expression System.out.println(e.toString()) is a void method call, and thus it cannot be parameterized
    41Expression e.printStackTrace() is a void method call, and thus it cannot be parameterized
    42Expression e cannot be parameterized, because it has dependencies to/from statements that will be extracted

    46Expression e.printStackTrace() is a void method call, and thus it cannot be parameterized
    47Expression d1 cannot be unified with expression kv2D1 , because common superclass type org.jfree.util.PublicCloneable cannot be passed as an argument to public abstract void writeObject(java.lang.Object) throws java.io.IOException
    48Unmatched statement kv2D2=(DefaultKeyedValues2D)in.readObject(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
    49Unmatched statement kv2D2=(DefaultKeyedValues2D)in.readObject(); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted
    50Unmatched statement d2=(KeyedValuesDataset)in.readObject(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
    51Unmatched statement d2=(KeyedValuesDataset)in.readObject(); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted
    52Expression d1 cannot be unified with expression kv2D1 , because common superclass type org.jfree.util.PublicCloneable cannot be passed as an argument to public static void assertEquals(java.lang.Object, java.lang.Object)
    53Type org.jfree.data.general.KeyedValuesDataset of variable d2 does not match with type org.jfree.data.DefaultKeyedValues2D of variable kv2D2
