Description Andrew Clement CLA 2009-06-17 17:12:02 EDT 
Playing around with incremental builds of generic ITDs.

java.lang.NullPointerException
at org.aspectj.weaver.NewFieldTypeMunger.equals(NewFieldTypeMunger.java:109)
at org.aspectj.weaver.ConcreteTypeMunger.equivalentTo(ConcreteTypeMunger.java:45)

at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

when I modified a declaration from:

int A<X,Y>.i;

to

int A.i;
Comment 1 Andrew Clement CLA 2009-06-17 17:26:25 EDT 
fixed that (was duff equals() code) - also fixed it for ITD methods
Comment 2 Andrew Clement CLA 2009-06-17 17:55:47 EDT 
and another:

java.lang.NullPointerException
at org.aspectj.weaver.ResolvedType.discoverActualOccurrenceOfTypeInHierarchy(ResolvedType.java:1369)
at org.aspectj.weaver.ResolvedType.fillInAnyTypeParameters(ResolvedType.java:1420)
at org.aspectj.weaver.ResolvedType.addInterTypeMunger(ResolvedType.java:1462)
at org.aspectj.ajdt.internal.compiler.lookup.AjLookupEnvironment.weaveInterTypeDeclarations(AjLookupEnvironment.java:687)
at org.aspectj.ajdt.inter ... oBuildJob.run(AutoBuildJob.java:238)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

going from this:
package p;

import java.util.List;

public class A<N extends Number, T> {
  public static void main(String[] args) {
	A a = new A();
	List<String> localls = a.ls;
	
}
}

to this (removing type vars)

package p;

import java.util.List;

public class A {
  public static void main(String[] args) {
	A a = new A();
	List<String> localls = a.ls;

}
}
Comment 3 Andrew Clement CLA 2009-06-18 14:37:13 EDT 
those were both fixed in 1.6.5
