      "message": "Refactor dexpreopt for boot jars to make it flexible to config changes.\n\nIn the past, dexpreopt for boot jars was very inflexible, and it was\nincredibly hard to make a change that is as simple as adding a jar to a\nboot image. Boot image generation was handled by\n\"platform_bootclasspath\" and \"bootclasspath_fragment\" separately. This\ncaused not only code duplication but also the inflexiblity as such a\ndesign did not fit today\u0027s use cases, where a boot image may take jars\nfrom multiple mainline modules and the platform, and a mainline module\ncan contribute to multiple boot images. The design casued a huge\nmaintenance burden as any change to the boot image cost multi-week\nefforts.\n\nIn recent years, efforts have been made to improve this a bit by a bit.\nThis change is another step towards making dexpreopt reasonable.\n\nAfter this change, all boot images are generated by \"dex_bootjars\",\nwhich is in build/soong and is therefore available on both the full\nsource tree and the thin manifest (master-art). The change decouples\nprofile generation/extraction from boot image generation. Profiles for\nmainline modules are still handled by \"bootclasspath_fragment\"\nbecause they need to be packed into APEXes when building mainline\nmodules and extracted from APEXes whem building the system image from\nprebuilt modules. Boot images are not handled by\n\"bootclasspath_fragment\" anymore.\n\nBug: 290583827\nTest: m (all existing tests are still passing)\nTest: Manually checked that the boot images are exactly the same as\n  before.\nChange-Id: Ib5a5f401bee334ffcab5c26618e0c8888b84575a\n"
