* [Bug java/18147] New: Objects in instance initializer blocks are scoped too widely @ 2004-10-25 18:46 csm at gnu dot org 2004-10-25 18:49 ` [Bug java/18147] " pinskia at gcc dot gnu dot org ` (2 more replies) 0 siblings, 3 replies; 5+ messages in thread From: csm at gnu dot org @ 2004-10-25 18:46 UTC (permalink / raw) To: java-prs If you declare an object within an instance initializer, you cannot declare another object of the same name in a different instance initializer. This description seems pretty opaque, so an example of correct code that GCJ rejects is probably better: -- init.java -- import java.util.HashMap; class init { private final HashMap _map1 = new HashMap(); { Object foo = new Object(); _map1.put ("foo!", foo); } private final HashMap _map2 = new HashMap(); { Object foo = new Object(); _map2.put ("bar!", foo); } } -- init.java -- GCJ exits with this error: init.java:13: error: Variable `foo' is already defined in this method and was declared `Object foo' at line 7. Object foo = new Object(); ^ 1 error -- Summary: Objects in instance initializer blocks are scoped too widely Product: gcc Version: 3.4.2 Status: UNCONFIRMED Severity: normal Priority: P2 Component: java AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: csm at gnu dot org CC: gcc-bugs at gcc dot gnu dot org,java-prs at gcc dot gnu dot org GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18147 ^ permalink raw reply [flat|nested] 5+ messages in thread

Instead, however, it should treat each as a separate block and chain the blocks together. That is, an instance initializer block introduces a new scope. -- What |Removed |Added ---------------------------------------------------------------------------- Keywords|rejects-valid | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18147 ^ permalink raw reply [flat|nested] 5+ messages in thread
