IncompatibleClassChangeError

AI-generated Key Takeaways

• IncompatibleClassChangeError signals an incompatible change in a class definition that the current method depends on.

• This error is a subclass of LinkageError and has several direct subclasses like AbstractMethodError and NoSuchFieldError which address specific incompatibility issues.

• It's thrown when the definition of a class has been altered after compilation, leading to conflicts during runtime.

• Two constructors are available: one with no detail message and another accepting a custom message describing the error.

public class IncompatibleClassChangeError extends LinkageError

Known Direct Subclasses AbstractMethodError, IllegalAccessError, InstantiationError, NoSuchFieldError, NoSuchMethodError AbstractMethodError Thrown when an application tries to call an abstract method.  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 new construct 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.

Thrown when an incompatible class change has occurred to some class definition. The definition of some class, on which the currently executing method depends, has since changed.

Public Constructor Summary

	IncompatibleClassChangeError() Constructs an IncompatibleClassChangeError with no detail message.
	IncompatibleClassChangeError(String s) Constructs an IncompatibleClassChangeError with the specified detail message.

Inherited Method Summary

From class java.lang.Throwable

synchronized final void	addSuppressed(Throwable exception) Appends the specified exception to the exceptions that were suppressed in order to deliver this exception.
synchronized Throwable	fillInStackTrace() Fills in the execution stack trace.
synchronized Throwable	getCause() Returns the cause of this throwable or null if the cause is nonexistent or unknown.
String	getLocalizedMessage() Creates a localized description of this throwable.
String	getMessage() Returns the detail message string of this throwable.
StackTraceElement[]	getStackTrace() Provides programmatic access to the stack trace information printed by printStackTrace().
synchronized final Throwable[]	getSuppressed() Returns an array containing all of the exceptions that were suppressed, typically by the try-with-resources statement, in order to deliver this exception.
synchronized Throwable	initCause(Throwable cause) Initializes the cause of this throwable to the specified value.
void	printStackTrace() Prints this throwable and its backtrace to the standard error stream.
void	printStackTrace(PrintWriter s) Prints this throwable and its backtrace to the specified print writer.
void	printStackTrace(PrintStream s) Prints this throwable and its backtrace to the specified print stream.
void	setStackTrace(StackTraceElement[] stackTrace) Sets the stack trace elements that will be returned by getStackTrace() and printed by printStackTrace() and related methods.
String	toString() Returns a short description of this throwable.

From class java.lang.Object

Object	clone() Creates and returns a copy of this Object.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of Class that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.
