There has been significant news related to JDK 12 in recent days.
JDK 12 Early Access Build 14
JDK 12 Early Access Build 14 (2018/10/4) was released today. The release notes indicate that the fix for JDK-8210692 ["The 'com.sun.awt.SecurityWarning' class can be dropped"] is a significant part of this build. The class
com.sun.awt.SecurityWarning, deprecated for removal with JDK 11, has now been removed altogether. Other links of interest related to OpenJDK 12 Early Access Build 12 include "Changes in this build" and "Issues addressed in this build". This build also includes, of course, the preview features switch expressions (JEP 325) and raw string literals (JEP 326) that I have blogged on previously.
