[aspectj-users] AJDT throws NullPointerException after adding cflow.
|
If I add cflow(validate()) into @AfterReturning, AJDT throws NPE. I list the class and message here. The maven project is also attached.
My environment:
Eclipse 3.5 buildid: 20100218-1602
AJDT 2.0.2.e35x-20100105-0900
package org.foo;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
@Aspect
public class CflowAspect {
@Pointcut("execution(boolean *..CflowExample.validateParameter(..))")
public void validate() {
}
@AfterReturning(pointcut = "call(boolean *..Properties.containsKey(Object)) && args(key) && cflow(validate())", returning = "existed")
public void afterCheckExistence(String key, boolean existed) {
System.out.println(key + " " + (existed ? "exists" : "doesn't exists"));
}
}
package org.foo;
import java.util.Properties;
public class CflowExample {
private boolean validateParameter(Properties config, String key) {
return config.containsKey(key);
}
public static void main(String[] args) {
Properties props = new Properties();
props.put("ABC", "data");
CflowExample example = new CflowExample();
example.validateParameter(props, "ABC");
example.validateParameter(props, "DEF");
}
}
java.lang.NullPointerException
