Color.getMatchingColorHexValue - causes Exception and contains System.out.println

[GoogleCodeExporter]

What steps will reproduce the problem?

de.toolforge.googlechartwrapper.Color c = new 
de.toolforge.googlechartwrapper.Color(255, 255, 255, 0);

String rgba = c.getMatchingColorHexValue();

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String 
index out of range: 8
    at java.lang.String.substring(Unknown Source)
    at de.toolforge.googlechartwrapper.Color.getEightCharacterHexValue(Color.java:175)
    at de.toolforge.googlechartwrapper.Color.getMatchingColorHexValue(Color.java:234)

What is the expected output? What do you see instead?

No exception and no output to std out.


What version of the product are you using? On what operating system?

revision 189, Win 7.


Please provide any additional information below.

As a work around, I replaced getEightCharacterHexValue with the following:

    public String getEightCharacterHexValue() {
        return String.format("%02x%02x%02x%02x", red, green, blue, alpha);
    }
