com.mebigfatguy.fbcontrib.detect.SuspiciousJDKVersionUse

All Implemented Interfaces:

edu.umd.cs.findbugs.Detector, edu.umd.cs.findbugs.Priorities, edu.umd.cs.findbugs.visitclass.Constants2, org.apache.bcel.classfile.Visitor, org.apache.bcel.Constants

public class SuspiciousJDKVersionUse
extends edu.umd.cs.findbugs.BytecodeScanningDetector

looks for calls to classes and methods that do not exist in the JDK for which this class is compiled. This can happen if you specify the -source and -target options of the javac compiler, and specify a target that is less than the jdk version of the javac compiler.
