Subject [jira] Commented: (HARMONY-6246) Crash during debugging session
Date Thu, 09 Jul 2009 10:57:14 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-6246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12729171#action_12729171

Oliver Deakin commented on HARMONY-6246:
----------------------------------------

It looks to me like we're running on the Harmony JDWP as the console dump includes:

c:\jdk\harmony-jdk-782693\jre\bin\jdwp.dll:
        0x01590000:0x015ba000
c:\jdk\harmony-jdk-782693\jre\bin\dt_socket.dll:
        0x01d50000:0x01d56000

I saw a failure the first time I ran a simple HelloWorld-with-variables type test [1] - when
I hovered over the variable name the debug session exited and the popup just said "a=<unknown>".
However I did not get a crash dump and since then the test has passed for me successfully
(whether I debug in Eclipse or launch at the command line and debug remotely). 

Hristo - could you provide the test case you were using please? Id like to track this failure
down and also figure out if it is fixed by the updated JDWP Im working on getting into the
Java 6 branch.
Thanks!

[1]
public class HelloWorld {
    public static void main(String[] args) throws Exception {
        System.out.println("HelloWorld");
        int a = 5;
        for (int i=0; i<10; i++) {
        	a++;
        }
        System.out.println("a="+a);
    }
}
