The following code snippet does not compile in Eclipse 3.0.1 or 3.1 (it however compiles in Eclipse 2.0.3 or with IBM or Sun JDK 1.4.2): public class test2 { public void test() { class C { public C() {} public void foo() { System.out.println("hello"); } } int n = 0; switch (n) { case 0: { C c2 = new C(); } } } } The following modifications make it work: 1. Adding another case 1: below case 0: that refers to C makes it compile. 2. Removing the inner scope in case 0: makes it work. 3. Moving the inner class C from the method scope to the test2 scope makes it work as well.
BTW, forgot to mention the compiler error message: Severity Description Resource In Folder Location Creation Time 2 C cannot be resolved or is not a type test2.java test line 27 March 8, 2005 19:01:05
Reproduced. This is indeed our bug.
When addressed, do you need this to be backported to 3.0.* maintenance stream ? i.e. how 'critical' is this ?
Problem got introduced when adding support for preventing referencing local types across switch case statement blocks (see bug 52221). Tuned implementation to handle this situation, and also possibly nested switch statements: public class X { public void test() { int l = 1; switch(l) { case 1: class C { public C() { } public void foo() { System.out.println("hello"); } } int n = 0; switch (n) { case 0 : if (true) { C c2 = new C(); } } } } } Added LookupTest#052-053. Fixed
We have a workaround for this problem where if this specific case happens, it can be compiled by the regular JDK that sits on the server. As such, it would not qualify for upgrading our current 3.0.1 workbench to have this fix in. The next window of opportunity to upgrade the workbench might probably be 3.1 already. So from our standpoint, it does not need to be backported to 3.0.x. Thanks for the quick turnaround.
Thanks for the assessment
