XYValueSeries.clear (or remove) generates a wrong .getMaxValue

What steps will reproduce the problem?
1.to initiate the XYValueSeries with some values. In this case getMaxValue 
works correctly. 
2.to clear the series with "clear" or "remove" until the series is empty. 
3.to rewrite the series again with some values. 
4.the Values are correct in the series, but getMaxValue returns the possibly 
maximum value of "double", which is 1.7976...E308. 

What is the expected output? What do you see instead?
The expected output of getMaxValue is to be the real max value in the series 
after the rewritting. Instead I see the max one of "double". 

Please provide a source code snippet that we can use to replicate the
issue.
