Getting IllegalArgumentException for null value in using Splitter KeyValueGenerator

I am using the guava Splitter as:

Splitter.on(",").withKeyValueSeperator(Splitter.on("=").limit(2)).split(<My required String>);

My input String is like:

A=1,B=2,C=null....

If none of value(1,2) for the key(A,B,C) is null then the above Splitter works fine otherwise it fails with "IllegalArgumentException: Chunk[>null] is not a valid entry"

Works OK for input you gave:

@Test
public void shouldSplitValues() {
    //given
    Splitter.MapSplitter mapSplitter = Splitter.on(",").withKeyValueSeparator("=");
    String input = "A=1,B=2,C=null";
    //when
    Map<String, String> result = mapSplitter.split(input);
    //then
    assertThat(result)
            .containsExactly(entry("A", "1"),
                             entry("B", "2"),
                             entry("C", "null"));
    // {A=1, B=2, C=null}
}

The message suggests it's the error in your input string, i.e. if

String input = "A=1,B=2,>null";

then I indeed get java.lang.IllegalArgumentException: Chunk [>null] is not a valid entry with the code above.
