method to return a list of exported linkers and declare the subclass in /META-INF/services/jdk.dynalink.linker.GuardingDynamicLinkerExporter

when a security manager is present, to ensure that only trusted runtimes can automatically export their linkers into other runtimes.Modifier and Type | Field | Description |
