7014261: G1: RSet-related failures
Summary: A race between the concurrent cleanup thread and the VM thread while it is processing the "expanded sparse table list" causes both threads to try to free the same sparse table entry and either causes one of the threads to fail or leaves the entry in an inconsistent state. The solution is purge all entries on the expanded list that correspond go regions that are being cleaned up.

| duke@435 | 3 | |
| trims@1907 | 4 | The OpenJDK source code made available by Oracle at openjdk.java.net and |
| duke@435 | 5 | openjdk.dev.java.net ("OpenJDK Code") is distributed under the terms of the |
| duke@435 | 6 | GNU General Public License <http://www.gnu.org/copyleft/gpl.html> version 2 |
| duke@435 | 7 | only ("GPL2"), with the following clarification and special exception. |
| duke@435 | 8 | |
| duke@435 | 9 | Linking this OpenJDK Code statically or dynamically with other code |
| duke@435 | 10 | is making a combined work based on this library. Thus, the terms |
| duke@435 | 11 | and conditions of GPL2 cover the whole combination. |
| duke@435 | 12 | |
| trims@1907 | 13 | As a special exception, Oracle gives you permission to link this |
| trims@1907 | 14 | OpenJDK Code with certain code licensed by Oracle as indicated at |
| duke@435 | 15 | http://openjdk.java.net/legal/exception-modules-2007-05-08.html |
| duke@435 | 16 | ("Designated Exception Modules") to produce an executable, |
| duke@435 | 17 | regardless of the license terms of the Designated Exception Modules, |
| duke@435 | 18 | and to copy and distribute the resulting executable under GPL2, |
| duke@435 | 19 | provided that the Designated Exception Modules continue to be |
| trims@1907 | 20 | governed by the licenses under which they were offered by Oracle. |
| duke@435 | 21 | |
| trims@1907 | 22 | As such, it allows licensees and sublicensees of Oracle's GPL2 OpenJDK Code to |
| trims@1907 | 23 | build an executable that includes those portions of necessary code that Oracle |
| trims@1907 | 24 | could not provide under GPL2 (or that Oracle has provided under GPL2 with the |
| duke@435 | 25 | Classpath exception). If you modify or add to the OpenJDK code, that new |
| duke@435 | 26 | GPL2 code may still be combined with Designated Exception Modules if the |
| duke@435 | 27 | new code is made subject to this exception by its copyright holder. |
