Hello!
Looking for reviews of this change: http://cr.openjdk.java.net/~allwin/7162400/webrev.01/ For CR: http://bugs.sun.com/view_bug.do?bug_id=7162400 https://jbs.oracle.com/bugs/browse/JDK-7162400 Summary: This change addresses an issue in the Attach API on Solaris, Linux and BSD where an attaching application can receive IOExceptions such as "Bad file number" (Solaris), "Connection refused" (Linux/BSD), or "well-known file is not secure". The attach process uses a file in the temporary directory as a door (Solaris) or domain socket (Linux,BSD) to communicate with the VM. In certain circumstances stale files can be left in the file system which can cause the attaching application to believe that the VM is ready to receive a connection when it's not. With this change the stale file will be removed during VM startup. Note that there is still an issue if we don't have permission to remove the stale file, the attaching process will fail to connect. Testing: JPRT, reproducing script on Solaris, Linux. Credits: Thanks to Staffan Larsen who worked on this issue with me. Regards, Peter
