Migrating Java UI Client Applications to OpenJDK 11
summary
OpenJDK 11 removes several closed-source pieces so Java UI apps often stop running without change: Lucida fonts removed breaks fallbacks and layouts, the proprietary JPEG codec and color profiles are gone (migration to LittleCMS changes color and can slow conversions), and JavaFX unbundled forces delivering FX on the module path. High-DPI uses FreeType/Harfbuzz and causes icon scaling and occasional rendering slowdowns. Migration path uses jlink+jpackage to build trimmed runtimes and convert JNLP/webstart apps to packaged native installers; test early and report issues.
