There is only one file with calibration data (machinedata.jdk15) for both Tiger and Mustang. There should be one special file with calibration data for each profiler java platform.
Fixed in M8, the calibration file names were cleaned up, all use machinedata.jdk<version> names. This is also a change for JDK 1.4, which now uses machinedata.jdk142 instead of machinedata, which will mean that the user will be prompted to calibrate even though he used modified 1.4.2 before.
