Class BackportReusePublicIdentifiers

  • 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 BackportReusePublicIdentifiers
    extends edu.umd.cs.findbugs.bcel.OpcodeStackDetector
    Detects use of backport libraries, when the code in question is compiled in a jdk that has the functionality available. Libraries include:
    • Use of Backport concurrent classes. Updated/Efficient version of these classes are available in versions of the JDK 1.5 and higher, and these classes should only be used if you are targeting JDK 1.4 and lower.
    • Use of ThreeTen time backport classes, instead of java.time packages which are now available in JDK 1.8 and higher, and these classes should only be used if you are targeting JDK 1.7 and lower
