GenericSignatureFormatError, UnsupportedClassVersionError

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.
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.

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.

Summary

Public constructors

Inherited methods

From class


        
          java.lang.Throwable

`final void`	`addSuppressed(Throwable exception)` Appends the specified exception to the exceptions that were suppressed in order to deliver this exception.
`Throwable`	`fillInStackTrace()` Fills in the execution stack trace.
`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()`.
`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.
`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)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
