Imports
sun.util.logging.PlatformLogger
Utility class for detecting inadvertent uses of boxing in java.util classes. The detection is turned on or off based on whether the system property org.openjdk.java.util.stream.tripwire is considered true according to Boolean#getBoolean(String). This should normally be turned off for production use.

API Note

Typical usage would be for boxing code to do: 

if (Tripwire.ENABLED)
        Tripwire.trip(getClass(), "{0} calling PrimitiveIterator.OfInt.nextInt()");
Since
