These Editions include all changes from Component JSR Specifications, namely JSR 335 (Lambda Expressions) and JSR 308 (Type Annotations). They also include two small features that are not themselves the subject of a Component JSR Specification: Access to Parameter Names at Runtime (JEP 118) and Repeating Annotations (JEP 120). Finally, they include all corrections and clarifications made since Java SE 7.
In each document, the differences between the Java SE 7 and 8 Editions are indicated by change bars and colored text, as follows:
Dark blue — Changes from JSR 335
Purple — Changes from JSR 308
Green — Changes for the two small features given above
Bright blue — Miscellaneous corrections to the Java SE 7 Edition
Red — Miscellaneous clarifications to the Java SE 7 Edition
Occasionally, where it is desirable to show the detail of a change, text from the Java SE 7 Edition is crossed out and the changed text is shown in dark blue, purple, green, or red as appropriate.
For the miscellaneous corrections and clarifications, background information is available in the JDK Bug System under the specification/language subcomponent, for the JLS, and the specification/vm subcomponent, for the JVMS.
