/**
 * Usage example:
 * // Creating an instance of JVMThrowable
 * const jvmThrowable = new JVMThrowable('ExceptionType', 'An exception occurred', 'stacktraceString', null);
 *
 * // Display information about the JVM throwable
 * console.log(jvmThrowable.type);          // Outputs: ExceptionType
 * console.log(jvmThrowable.message);       // Outputs: An exception occurred
 * console.log(jvmThrowable.stacktrace);    // Outputs: stacktraceString
 * console.log(jvmThrowable.cause);         // Outputs: null (since no cause is provided here)
 *
 * // Serializing JVMThrowable instance to a JSON object
 * const jvmThrowableJson = jvmThrowable.toJson();
 * console.log(jvmThrowableJson); // Outputs: { type: 'ExceptionType', message: 'An exception occurred', stacktrace: 'stacktraceString', cause: null }
 *
 * const jvmThrowableData = {
 *   type: 'RuntimeException',
 *   message: 'Failed to load resource',
 *   stacktrace: 'stacktrace info here',
 *   cause: null // Alternatively, you could nest another throwable here if there is one
 * };
 *
 * // Deserializing the parsed JSON into instance JVMThrowable
 * const deserializedJVMThrowable = JVMThrowable.fromJson(jvmThrowableData);
 * console.log(deserializedJVMThrowable);
