Right. And it was never intended to allow an app to provide the CMM ..
it was just
for choosing between built-in ones.
We probably can ditch the code that reads the property now since it
hasn't had any purpose since (IIRC) JDK 9.
Perhaps - if you believe it is really a LCMS issue, that you start by
reporting your problem to
the upstream littlecms project.
But if it is a JDK-specific issue in the way we use LCMS or the profiles
bundled with OpenJDK
then you should file a JDK bug report at

Hello Alex,
This option (-Dsun.java2d.cmm ) was implemented to switch between
proprietary Color Management library from Kodak and open source Little
CMS during transition JDK to open source (See
https://bugs.openjdk.org/browse/JDK-6476534 for more info). Another
candidate was Sample ICC (https://www.color.org/sampleicc.xalter) but
it is C++ not java.
Best Regards,
Alexey

Hello,
I am sorry for the wide distribution or if I am reaching out to the
wrong group.
I am running into issues with using awt/java2d color conversion
between ICC profiles.
It seems to be boiling down to the native library (little-csm) used
in java2d.cmm.lcms by default.
At the same time I think there is an option -Dsun.java2d.cmm
defaulting to sun.java2d.cmm.lcms.LcmsServiceProvider, hence it feels
that there could be other providers, hopefully not dependent on
little-csm. But I was not able to find any.
Question: Are there known alternatives to
sun.java2d.cmm.lcms.LcmsServiceProvider, which can be used as an
override, with -Dsun.java2d.cmm option. Preferably a pure-java
implementation, even though it will be slower.
Thank you,
