As part of the fix for 5037596 the native functions for doing non-raw conversions of floatToIntBits and doubleToLongBits are being removed. hotspot has a dependence on these functions though their usage is completely dead since 1.3.1. JVM_SetPrimtiveFieldValues and JVM_GetPrimitiveFieldValues are the only users and these are exported from library globally. These are bound to java.io.ObjectInputStream.setPrimitiveFieldValues and ObjectOutputStream.getPrimtiveFieldValues which hasn't existed in the sources since 1.3.1.
