[ BUILD # : 200903191401 ]
[ JDK VERSION : 1.6.* ]

Steps to reproduce:
1. Open a Java project
2. Activate a debug action
3. When "debug:" appears on "Output" TC, click on "Stop"

Expected behaviour:
* Debug is cancelled, interface revers to "normal" (i.e. no debug
toolbar or TCs)

Actual behaviour:
* shmemBase is created, debug perspective is activated, but no debug
session is started. If we activate a debug action again, this
exception occurs:

java.io.IOException: shmemBase_listen failed: Não é possível criar um
arquivo já existente
