Description Jaroslav Tulach 2009-02-04 16:52:51 UTC 
PS: Startup is slower by 10s in recent measurements.

A lot of new JNA classes is loaded on start. Why? I would expect them to be needed only during d'n'd not during start 
itself. These are new since last measurement done at M1:

    com.sun.jna.AltCallingConvention
    com.sun.jna.Callback
    com.sun.jna.FromNativeContext
    com.sun.jna.FromNativeConverter
    com.sun.jna.Function
    com.sun.jna.Function$PostCallRead
    com.sun.jna.FunctionMapper
    com.sun.jna.FunctionParameterContext
    com.sun.jna.FunctionResultContext
    com.sun.jna.IntegerType
    com.sun.jna.Library
    com.sun.jna.Library$Handler
    com.sun.jna.Library$Handler$FunctionInfo
