Examples with MethodHandles.publicLookup java.lang.invoke.MethodHandles.publicLookup used on opensource projects

Example 1 with MethodHandles.publicLookup

use of java.lang.invoke.MethodHandles.publicLookup in project openj9 by eclipse.

the class LookupInTests method testLookup_inObject_Using_publicLookup.

/**
 * Using an old lookup object that was created from a call to MethodHandles.publicLookup(),
 * validates access restrictions stored in a new Lookup object created from an old Lookup object
 * where the new lookup class is java.lang.Object.
 * @throws Throwable
 */

    Lookup lookup = PackageExamples.getPublicLookup();
    Lookup inObject = lookup.in(int.class);
    /*NOTE:
		 * This is equivalent of the failing test case above, but this one works.
		 * The only difference is here we are using MethodHandles.publicLookup() 
		 * instead of MethodHandles.lookup() to obtain the original Lookup object.
		 * */
    assertClassAndMode(inObject, int.class, MethodHandles.Lookup.PUBLIC);
}
