org.apache.juneau.commons.reflect.BeanRuntimeException

All Implemented Interfaces:

Serializable

public class BeanRuntimeException
extends RuntimeException

A RuntimeException wrapper around common reflection exceptions.

This exception is used to wrap checked exceptions that commonly occur when using Java reflection APIs, converting them into unchecked exceptions for easier handling in bean-processing code.

Wrapped Exceptions:

• InstantiationException
• IllegalAccessException
• IllegalArgumentException
• InvocationTargetException
• NoSuchMethodException
• SecurityException

The exception message can optionally include the class name of the bean that caused the exception, making it easier to identify the source of reflection errors in complex bean hierarchies.

Example:

try { Constructor<?> c = MyBean.class.getConstructor(); c.newInstance(); } catch (Exception e) { throw new BeanRuntimeException(e, MyBean.class, "Failed to instantiate bean"); }
