@mrserb 
Non-header data are updated using cooked approach (and validated by LCMS) whereas header data are updated using raw LCMS APIs hence require additional validation before setData() is called (On native side it is handled here: setTagDataNative() in [LCMS.c](https://github.com/openjdk/jdk/blob/63eb4853f6782f350f67b6bcf25d83bc4480be71/src/java.desktop/share/native/liblcms/LCMS.c#L445)).

Without the fix, if  invalid rendering intent, PCS, ColorSpace or Device class is updated using setData()  it does not throw IAE.
