RFR: 8366208: Unexpected exception in sun.java2d.cmm.lcms.LCMSImageLayout

Fri Aug 29 00:15:59 UTC 2025

We have a few places in the cmm code where the fast-code-path assumes that standard buffered images with type such as TYPE_INT_ARGB_PRE use our private raster implementation such as IntegerComponentRaster, which is not necessarily true. Casting to these private raster types can result in a ClassCastException.

The patch will detect such custom images and fall back to the slow path for conversion.
