Class TransformerFactoryDetector

  • All Implemented Interfaces:
    edu.umd.cs.findbugs.Detector, edu.umd.cs.findbugs.Priorities, org.apache.bcel.classfile.Visitor
    public class TransformerFactoryDetector
extends edu.umd.cs.findbugs.bcel.OpcodeStackDetector
    Currently the detector look for a specific code sequence. If the value is not hardcoded or computed at runtime, it will be consider as possibly unsafe. Minimal effort was put in this detector to avoid giving a lot of resource for code section that usually all look the same. Do note that the "safe" state for the TransformerFactory doesn't prevent denial of service attack like the LoL Bomb.
