org.apache.harmony.misc.accessors.LockedArray
Wraps the locked primitive type array. Holds a reference to Array object and its memory location. Objects of this type require a manual disposal through the {@link #release()}method. Please note that the array address is no longer valid after the {@link #release()}call is made.
Locked arrays can only be obtained with help of {@link ArrayAccessor} class. @see ArrayAccessor
