> This is an update to javac and javadoc, to introduce support for Preview > APIs, and generally improve javac and javadoc behavior to more closely adhere > to JEP 12. > > The notable changes are: > > * adding support for Preview APIs (javac until now supported primarily only > preview language features, and APIs associated with preview language > features). This includes: > * the @PreviewFeature annotation has boolean attribute "reflective", > which should be true for reflective Preview APIs, false otherwise. This > replaces the existing "essentialAPI" attribute with roughly inverted meaning. > * the preview warnings for preview APIs are auto-suppressed as described > in the JEP 12. E.g. the module that declares the preview API is free to use > it without warnings > * improving error/warning messages. Please see [1] for a list of > cases/examples. > * class files are only marked as preview if they are using a preview > feature. [1] also shows if a class file is marked as preview or not. > * the PreviewFeature annotation has been moved to jdk.internal.javac package > (originally was in the jdk.internal package). > * Preview API in JDK's javadoc no longer needs to specify @preview tag in > the source files. javadoc will auto-generate a note for @PreviewFeature > elements, see e.g. [2] and [3] (non-reflective and reflective API, > respectively). A summary of preview elements is also provided [4]. Existing > uses of @preview have been updated/removed. > * non-JDK javadoc is also enhanced to auto-generate preview notes for uses > of Preview elements, and for declaring elements using preview language > features [5]. > > Please also see the CSR [6] for more information. > > [1] http://cr.openjdk.java.net/~jlahoda/8250768/JEP12-errors-warnings-v6.html > [2] > http://cr.openjdk.java.net/~jlahoda/8250768/jdk.javadoc.00/api/java.base/java/lang/Record.html > [3] > http://cr.openjdk.java.net/~jlahoda/8250768/jdk.javadoc.00/api/java.compiler/javax/lang/model/element/RecordComponentElement.html > [4] > http://cr.openjdk.java.net/~jlahoda/8250768/jdk.javadoc.00/api/preview-list.html > [5] http://cr.openjdk.java.net/~jlahoda/8250768/test.javadoc.00/ > [6] https://bugs.openjdk.java.net/browse/JDK-8250769
