No diamonds here..
See bug 99931.
The problem seems to be here: org.eclipse.jdt.internal.corext.refactoring.code.IntroduceIndirectionRefactoring.qualifyThisExpression(ThisExpression expr, MethodInvocation originalInvocation, IMember enclosing, CompilationUnitRewrite unitRewriter) where it tries to set a qualifier with the type parameters, whereas it only needs to use 'this' qualifier. Need to check if the type binding is wrong(core) or the logic we use to compare the bindings and calculate the qualifier to be set(UI).
Created attachment 199100 [details] Patch (In reply to comment #3) > The problem seems to be here: > > org.eclipse.jdt.internal.corext.refactoring.code.IntroduceIndirectionRefactoring.qualifyThisExpression(ThisExpression > expr, MethodInvocation originalInvocation, IMember enclosing, > CompilationUnitRewrite unitRewriter) > The code here expr.setQualifier(unitRewriter.getAST().newSimpleName(currentTypeBinding.getName())); currentTypeBinding.getName() gets the parameterized type name (HashMap<String, String>) and hence leads to an error. If it is parameterized it should simply use 'this' qualifier from the else block. I think we should fix this in BETA_JAVA7 in eventually in HEAD. Tests coming up.
Created attachment 199270 [details] Fix First patch is not good. It e.g. breaks IntroduceIndirectionTests#test04() when you change "public class Foo" to "public class Foo<T>". The problem is not that the type is parameterized, but that we compare it to typeOfCall, which is a declaration type binding. Normalizing the currentTypeBinding solves the problem.
Released the fix to BETA_JAVA7. Raksha, please add a test for your example, and a copy of test04() where Foo has a type parameter (attach a patch here, release to BETA_JAVA7, and close the bug).
