[allon2]

when i read the pl.pojo.tester.internal.utils.MethodUtils,
i found the upperCaseFirstLetter function don't support the setter and getter function like below
,can support it?

xCoordinate/Double | public Double getxCoordinate() |public void setxCoordinate(Double newValue)

when the first letter is lowercase and the second letter is UpperCase，follow the get or set letters is lowercase charater
