NumberFormatException when requesting JiraSoapService.getConfiguration(token) if eg Hours per day is set to 7.5

description:
the field RemoteConfiguration.timeTrackingHoursPerDay within the soap wsdl is of type 'int' but it is possible to enter double values like '7.5' within Global Settings/Time Tracking/Hours per day. This will lead to a NumberFormatException

to reproduce:
1. Go to Global Settings/Time Tracking and enable it
2. Change the 'Hours per day' value to '7.5' (decimal is important!)
3. click Activate
4. build a soap client and request JiraSoapService.getServerInfo(<token>)

this will lead to the following exception:
AxisFault
faultCode:
