BETA_JAVA8: This ER will be used to track problem method generation for lambdas. At the moment, these are not generated. I am not marking this bug as blocking bug 400875 since this is a second order problem.
Please use the test case from https://bugs.eclipse.org/bugs/show_bug.cgi?id=404657#c14. Once this problem is fixed, we would expect to see two errors instead of one in that test case. For investigation, try compiling and running this code as well as studying the bytecodes generated: // -- illustrates public class X { void foo () { goo(); } public static void main(String[] args) { System.out.println("Hello"); new X().foo(); } } See ClassFile#addProblemMethod and AbortMethod
Multiple lambda expressions with different compiler issues when present in a compilation unit then only one error is shown and the rest are ignored. Consider the below code snippet which shows only one compiler issues, whereas it should have shown 4 compiler errors: @FunctionalInterface interface I { int foo(int x); } public class D{ I i2= (int x) -> { x++; System.out.println(x);// Error 1: Should get a compiler error here as the return statement is missing }; public int foo1() { // Error 2: Should get a compiler error here due to missing return type I i2= (int x) -> { return "String"; // Error 3: Compiler error due to return type mismatch }; } public String foo2() { // Error 4: Should get a compiler error here due to missing return type } }
Retargetting to 4.4, will pull it up to Java 8 GA if time permits.
Shankha, please take a look.
Bulk move out of 4.8
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
