8012556: Implement lambda methods on interfaces as static
8006140: Javac NPE compiling Lambda expression on initialization expression of static field in interface
Summary: Lambdas occurring in static contexts or those not needing instance information should be generated into static methods. This has long been the case for classes. However, as a work-around to the lack of support for statics on interfaces, interface lambda methods have been generated into default methods. For lambdas in interface static contexts (fields and static methods) this causes an NPE in javac because there is no 'this'. MethodHandles now support static methods on interfaces. This changeset allows lambda methods to be generated as static interface methods. An existing bug in Hotspot (8013875) is exposed in a test when the "-esa" flag is used. This test and another test that already exposed this bug have been marked with @ignore.

| aoqi@0 | 3 | |
| aoqi@0 | 4 | The OpenJDK source code made available by Sun at openjdk.java.net and |
| aoqi@0 | 5 | openjdk.dev.java.net ("OpenJDK Code") is distributed under the terms of the |
| aoqi@0 | 6 | GNU General Public License <http://www.gnu.org/copyleft/gpl.html> version 2 |
| aoqi@0 | 7 | only ("GPL2"), with the following clarification and special exception. |
| aoqi@0 | 8 | |
| aoqi@0 | 9 | Linking this OpenJDK Code statically or dynamically with other code |
| aoqi@0 | 10 | is making a combined work based on this library. Thus, the terms |
| aoqi@0 | 11 | and conditions of GPL2 cover the whole combination. |
| aoqi@0 | 12 | |
| aoqi@0 | 13 | As a special exception, Sun gives you permission to link this |
| aoqi@0 | 14 | OpenJDK Code with certain code licensed by Sun as indicated at |
| aoqi@0 | 15 | http://openjdk.java.net/legal/exception-modules-2007-05-08.html |
| aoqi@0 | 16 | ("Designated Exception Modules") to produce an executable, |
| aoqi@0 | 17 | regardless of the license terms of the Designated Exception Modules, |
| aoqi@0 | 18 | and to copy and distribute the resulting executable under GPL2, |
| aoqi@0 | 19 | provided that the Designated Exception Modules continue to be |
| aoqi@0 | 20 | governed by the licenses under which they were offered by Sun. |
| aoqi@0 | 21 | |
| aoqi@0 | 22 | As such, it allows licensees and sublicensees of Sun's GPL2 OpenJDK Code to |
| aoqi@0 | 23 | build an executable that includes those portions of necessary code that Sun |
| aoqi@0 | 24 | could not provide under GPL2 (or that Sun has provided under GPL2 with the |
| aoqi@0 | 25 | Classpath exception). If you modify or add to the OpenJDK code, that new |
| aoqi@0 | 26 | GPL2 code may still be combined with Designated Exception Modules if the |
| aoqi@0 | 27 | new code is made subject to this exception by its copyright holder. |
