Tom Calderwood reported this at startup with OpenJDK 11 on Ubuntu:

libpng warning: iCCP: known incorrect sRGB profile

That libpng warning refers to the presence of a particular chunk in a PNG file. That chunk can apparently be removed, e.g. see https://www.fmeextensions.com/blog/libpng-warning-iccp-known-incorrect-srgb-profile/

This could be coming from any of:

./extlib/vstaricon.png
./bin/vstaricon.png
./bin/org/aavso/tools/vstar/ui/resources/images/citizen_sky.png
./bin/org/aavso/tools/vstar/ui/resources/icons/vstaricon.png

This corresponds to 2 files:

  • vstaricon.png
  • citizen_sky.png

The warning seems harmless. Could close this if we don't plan to fix it.
