43. @HendrikEbbers Java is not "only Oracle" anymore

44. @HendrikEbbers AWT & Swing

45. @HendrikEbbers AWT & Swing

46. Karakun DevHub_ @HendrikEbbersdev.karakun.com Swing & AWT • Swing and AWT won't used for new projects anymore • Stable APIs and no new features needed

47. Karakun DevHub_ @HendrikEbbersdev.karakun.com Swing & AWT • But: the private API will change from time to time • Replace native rendering engine based on os changes • Toolkits need support in future • Who will do that???

58. @HendrikEbbers Java is open source! I don't care

59. @HendrikEbbers Oracle Java != OpenJDK

60. Karakun DevHub_ @HendrikEbbersdev.karakun.com Oracle JDK & OpenJDK OpenJDK 8 JVM, tools, etc. JVM, tools, etc. Exclusive Oracle stuﬀ eg. Flight recorder WebStart Mission Control Oracle JDK 8

61. Karakun DevHub_ @HendrikEbbersdev.karakun.com Oracle JDK & OpenJDK OpenJDK 12 Oracle JDK 12 JVM, tools, etc. equals JVM, tools, etc.

62. Karakun DevHub_ @HendrikEbbersdev.karakun.com AdoptOpenJDK to the rescue!

71. Karakun DevHub_ @HendrikEbbersdev.karakun.com Alternative

72. @HendrikEbbers JavaFX

73. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX today • You can use JavaFX today without any problems

74. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX today • You can use JavaFX today without any problems • Since it is "just software" bugs will pop up over time

75. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX today • You can use JavaFX today without any problems • Since it is "just software" bugs will pop up over time • … and security issues

76. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX today • You can use JavaFX today without any problems • Since it is "just software" bugs will pop up over time • … and security issues • … and private API / native code must be changed

77. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX today • Such issues must be targeted in future and LTS versions • Currently companies provides LTS support for JavaFX 8 and 11

78. @HendrikEbbers What version of JavaFX are you using?

79. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX support - Azul https://docs.azul.com/zulu/zulurelnotes/ZuluReleaseNotes/CVE_Fixes_November19.htm

80. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX support - Oracle https://bugs.openjdk.java.net/

81. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX support - Gluon https://github.com/openjdk/jfx/blob/master/doc-files/release-notes-11.md

82. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX support - Bellsoft https://bell-sw.com/pages/liberica-release-notes-11.0.5/

83. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX 8 Issues JDK-8215702 JDK-8215799 JDK-8213806 JDK-8218611 JDK-8217942 JDK-8207772 SVG gradients are not rendered Complex text is not rendered by webkit on Windows WebView - JVM crashes for given HTML fast/xslt tests fails with "Unsupported encoding windows-1251" error Upgrade to libxslt 1.1.33 File API and FileReader should be supported in WebView

85. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX 8 @ AdoptOpenJDK • We got often asked why we do not add JavaFX to the Java 8 binaries • We only want to provide secure / up-to-date binaries • There is not open source JavaFX 8 development

86. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX 11 Issues Azul ZuluOracle JDK Amazon CorrettoGluon JavaFX JDK-8229328 Bellsoft JDK-8222912 JDK-8133841 JDK-8218611 JDK-8217942 JDK-8207772 V12/13 v12/13 v12/13 v12/13 v12/13 v12/13 V11 V11 V11 V11 V11 V11

87. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX 11+ • When using Java(FX) 11+ you should add JavaFX as a dependency • Using a JVM with integrated JavaFX is not the preferred solution

88. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX 11+ • Maybe Oracle is only interested in JavaFX until the LTS support of Java 8 ends • Today Oracle needs to contribute to JavaFX (based on the commercial support for Java 8)

92. @HendrikEbbers Kudos to

93. Karakun DevHub_ @HendrikEbbersdev.karakun.com JavaFX 14+ • There is a good chance that JavaFX 14 will run with Java 11 • No one knows if JavaFX 15 will still be compatible
