Please review JDK-8139895 "Introduce GuardingDynamicLinkerExporter" at
<http://cr.openjdk.java.net/~attila/8139895/webrev.jdk9> for
<https://bugs.openjdk.java.net/browse/JDK-8139895>
Remarks:
- DynamicLinkerFactory now loads the linkers in a doPrivileged block so that
the lack of “dynalink.exportLinkersAutomatically” permission in the caller
doesn’t preclude it from loading trusted linkers. This is consistent with how
e.g. ScriptEngineManager uses ServiceLoader.
- DynamicLinkerFactory now has a new method "List<ServiceConfigurationError>
getAutoLoadingErrors()” so that the user can inspect if some automatically loaded linkers
failed to load. This is especially significant as the GuardingDynamicLinkerExporter can
have some failure modes: it can lack the dynalink.exportLinkersAutomatically permission,
it can return null from get() or any element of the returned element might be null
Thanks,
Attila.
