ExceptionUtils provides a static method that will throw a checked exception as if it were a runtime exception. You can use this to catch and re-throw a checked exception without wrapping it in a RuntimeException and muddying up the stack trace.

ExceptionUtils.java

public class ExceptionUtils {
  public static void throwException(Exception ex) {
    if (ex instanceof RuntimeException) throw (RuntimeException)ex;
    
    try {
      synchronized (CheckedExceptionThrower.class) {
        CheckedExceptionThrower.exception = ex;
        CheckedExceptionThrower.class.newInstance();
      }
    } catch (InstantiationException | IllegalAccessException e) {
      throw new RuntimeException(e);
    }
  }
  
  private static class CheckedExceptionThrower {
    private static Exception exception;
    
    CheckedExceptionThrower() throws Exception {
      Exception ex = exception;
      exception = null;
      throw ex;
    }
  }
}
