    open class LinkageError : Error
    
    
      
        
          | Known Direct Subclasses
              
              
                
                  
                    | BootstrapMethodError | Thrown to indicate that an invokedynamicinstruction or a dynamic constant failed to resolve its bootstrap method and arguments, or forinvokedynamicinstruction the bootstrap method has failed to provide a call site with a target of the correct method type, or for a dynamic constant the bootstrap method has failed to provide a constant value of the required type. |  
                    | ClassCircularityError | Thrown when the Java Virtual Machine detects a circularity in the superclass hierarchy of a class being loaded. |  
                    | ClassFormatError | Thrown when the Java Virtual Machine attempts to read a class file and determines that the file is malformed or otherwise cannot be interpreted as a class file. |  
                    | ExceptionInInitializerError | Signals that an unexpected exception has occurred in a static initializer. |  
                    | IncompatibleClassChangeError | Thrown when an incompatible class change has occurred to some class definition. |  
                    | NoClassDefFoundError | Thrown if the Java Virtual Machine or a ClassLoaderinstance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using thenewexpression) and no definition of the class could be found. |  
                    | UnsatisfiedLinkError | Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native. |  
                    | VerifyError | Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem. |  | 
      
    
    
      
        
          | Known Indirect Subclasses
              
              
                
                  
                    | AbstractMethodError | Thrown when an application tries to call an abstract method. |  
                    | GenericSignatureFormatError | Thrown when a syntactically malformed signature attribute is encountered by a reflective method that needs to interpret the generic signature information for a type, method or constructor. |  
                    | IllegalAccessError | Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to. |  
                    | InstantiationError | Thrown when an application tries to use the Java newconstruct to instantiate an abstract class or an interface. |  
                    | NoSuchFieldError | Thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field. |  
                    | NoSuchMethodError | Thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method. |  
                    | UnsupportedClassVersionError | Thrown when the Java Virtual Machine attempts to read a class file and determines that the major and minor version numbers in the file are not supported. |  | 
      
    
    Subclasses of LinkageError indicate that a class has some dependency on another class; however, the latter class has incompatibly changed after the compilation of the former class.
