How to catch all uncatched exceptions with aspectj?

Question

Java

After searching for information, I came across a similar design

@AfterThrowing(pointcut = "execution(* com.mycompany.package..* (..))", throwing = "ex")

But the problem is that such a pointcut catches ALL exceptions. Regardless of whether we processed them or not. Is it possible to force aspectj to catch unhandled exceptions?

Toster.java

package com.toster.dao;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Toster {
}

TosterAspect.java

package com.toster.dao;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Aspect
public class TosterAspect {

    private static final Logger LOG = LoggerFactory.getLogger(TosterAspect.class);

    @Around("execution(* *(..)) && @annotation(tr)")
    public Object request(final ProceedingJoinPoint pjp, final Toster tr) throws Throwable {
        try {
            LOG.info("Invoke {}", pjp.toShortString());
            final Object proceed = pjp.proceed();
            LOG.info("Return {}", proceed);
            return proceed;
        } catch (Exception e) {
            LOG.error("Error", e);
            throw e; //TODO
        }
    }

}

AspectConfiguration.java

package com.toster.dao;

import org.aspectj.lang.Aspects;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;

@Configuration
@EnableAspectJAutoProxy
public class AspectConfiguration {

    @Bean
    public TosterAspect tosterAspect() {
        return Aspects.aspectOf(TosterAspect.class);
    }

}
