Bayan watanni shida na ci gaba, Oracle ya fito da dandalin Java SE 19 (Java Platform, Standard Edition 19), wanda ke amfani da bude tushen aikin OpenJDK azaman aiwatar da tunani. Ban da cire wasu fasalolin da aka yanke, Java SE 19 yana kula da dacewa da baya tare da abubuwan da suka gabata na dandalin Java - yawancin ayyukan Java da aka rubuta a baya za su yi aiki ba tare da canje-canje ba yayin da suke gudana ƙarƙashin sabon sigar.
