I just had this problem recently myself. The trick seems to be to
change the AspectJ dependencies for the aspectj-maven-plugin. My
config is below, but I use a private repo, so your artifacts would
likely be different:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<dependencies>
<dependency>
<groupId>aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.6.1</version>
</dependency>
<dependency>
<groupId>aspectj</groupId>
<artifactId>aspectjtools</artifactId>
<version>1.6.1</version>
</dependency>
</dependencies>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
</execution>
</executions>
<configuration>
<showWeaveInfo>true</showWeaveInfo>
<verbose>true</verbose>
<complianceLevel>1.5</complianceLevel>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>

Hi Joel,
That is certainly fixed in more recent builds, I just tried it:

no errors.
However, I don't know how to adjust your maven stuff...

I have an interface like this:
public interface EventListener<EVENTTYPE>
{
<EV extends EVENTTYPE> void handle(EV event);
}
And I'm creating a class that implements it such as:
EventListener<SomeEvent> s = new EventListener<SomeEvent>() {
public <V extends SomeEvent> void
handle(final V event)
{
// ...
}
}
I have tried it in non-anonymous case as well.
Compilation gives an error saying:
The type new EventListener<SomeEvent>(){} must implement the inherited
abstract method EventListener<SomeEvent>.handle(EV)
When using the eclipse or javac compiler, there is no error.
To complicate the question, I'm using maven for build, this for the
compiler:
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</
artifactId>
<version>1.1-SNAPSHOT</version>
And I think that results in aspectj 1.5.4 being used, though if you
know how to change it so it will use more recent, please tell me.
Thanks!
