Re: [aspectj-dev] exceptions and around

["Ron Bodkin" <rbodkin@xxxxxxxxxxxxxx>]

Eric,

Remember that if you soften the exception, it will be rethrown as a SoftException. So depending on the join point at which you soften, you may need to catch a SoftException. This code works for me:

import java.io.IOException;

aspect TestSoften {
    pointcut scope() : call(void testThrowIO());

    declare soft: IOException: scope();

    void around(): scope() {
	try {
	    proceed();
	}catch(org.aspectj.lang.SoftException x) {
	    System.out.println("file does not exist.");
	}
    }

    public static void main(String args[]) { testThrowIO(); }

    static void testThrowIO() throws IOException {
	throw new IOException();
    }

}
