NoClassDefFoundError is a fatal error. It occurs when JVM can not find the definition of the class while trying to:

Instantiate a class by using the new keyword Load a class with a method call The error occurs when a compiler could successfully compile the class, but Java runtime could not locate the class file. It usually happens when there is an exception while executing a static block or initializing static fields of the class, so class initialization fails.
