| # Tips and tasks when updating LittleCMS sources to a newer version. | |
| Download and unzip latest release from https://sourceforge.net/projects/lcms/files/ | |
| Replace files in src/java.desktop/share/native/liblcms with files from unzipped src and include folders | |
| Replace is important because the lcms sources here are just the subset needed by JDK. | |
| This is deliberate, so when updating be sure to import only the same files. | |
| If a file has been removed from upstream you will notice it during the copy. | |
| It should then be removed from the JDK sources. | |
| If a new file is needed then the build will fail. Manually copy that in. | |
| Some re-editing of these updated files will be needed. | |
| Use "expand" and "sed" to remove tabs and trailing white space from the imported files. | |
| Re-apply the GPL headers used by the JDK. If done correctly these should then not | |
| show up in the PR diff. | |
| Update src/java.desktop/share/legal/lcms.md per the current license/copyrights/attributions etc. | |
| Build on all platforms. | |
| If there are compiler warnings causing build failures, update the disabled warnings in | |
| make/modules/java.desktop/lib/Awt2dLibraries.gmk | |
| Run all automated client tests on all platforms. | |
| Also run J2Ddemo and pay particular attention to the "color" tab. | |
| Visually verify the color transforms against the same with the current/previous JDK |
