Example 66 with Lookup

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

Example 68 with Lookup

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

Example 69 with Lookup

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

the class LookupInTests method testLookup_ProtectedInnerClassLookup_CrossPackage.

Example 70 with Lookup

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

the class LookupInTests method testLookup_SamePackageLookup_Subclass.
