Hi Hristo,
It appears the crash happened in Harmony JVM. Can you see this crash intermittently or consistently? If it happens consistently, it would be great if you can provide some info about the steps of reproducing this problem. Thanks.

Gregory Shimansky commented on HARMONY-6246:
--------------------------------------------
Just a guess, that since crash happens while allocating new memory, it happens because of some memory corruption. This might happen because of VM's behavior or JPDA agent which is loaded into VM address space. It would be much more helpful to run debug build of Harmony and therefore see stack trace with line numbers.
I also wonder if JPDA agent from Sun's VM is loaded into Harmony VM... Theoretically it should work alright, but who knows, especially in case it is 6.0 version.

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);
}
}

Hi Hristo,
I guess the different version vm is not the cause, or it may throw a bad command exception (if it calls a java6 jdwp command). It seems a problem of threading adjusting(maybe suspend the thread to read the threadlocal or something), need to investigate if it is a jdwp or vm issue.
BTW Harmony6 JDWP is going to committed into the codebase(Oliver is the owner of the task) and it enhance the feature and fixes several bugs, I guess maybe you can try it if the fix for this problem does not come out quickly.

Hi,
I was able to produce a relatively small testcae (several classes), because Harmony did not crashed with pretty small tests.
I reproduced the issue with IntelliJ Idea (http://download.jetbrains.com/idea/idea10558.exe) when I tried to expand the LinkedHashSet on line 38 in com.sap.engine.bootstrap.Test class. I guess it should be the same with Eclipse.
To reproduce the issue I did the following (perhaps some of the steps are not needed but anyway):
* run the suspended test on another machine
* set breakpoint at the first line
* connect to the test remotely
* step in until i reached readPackageIndex method
* try to pop-up and expand every more complex-looking variable
Attached you will find the the test case and the produced minidump.
Regards,
Hristo Iliev

----------------------------------------
Hi Hristo,
I ran the test and took the Test.java from test.zip to do the debugging in Eclipse, but Im not sure the code actually matches up with what the Test.class in the jar file is doing. The test run produces a lot of output like:
Writing packages for [/usr/sap/BKP/J16/j2ee/cluster/bin/services/developmentserver_environment/development~server~environment.jar] took [16] ms
Writing packages for [/usr/sap/BKP/J16/j2ee/cluster/bin/ext/com.sap.xi.gui.lib/lib/private/com.sap.xpi.ib.upload.core.jar] took [16] ms

Writing packages for [/usr/sap/BKP/J16/j2ee/cluster/bin/ext/com.sap.tc.cmi/lib/com.sap.tc.cmi_api.jar] took [31] ms
Writing packages for [/usr/sap/BKP/J16/j2ee/cluster/bin/ext/ct.siemens.de~ctp~j2ee_bsm/dxmSPML-1.4.jar] took [47] ms
but the actual contents of Test.java seem to try and list the c:\inbox directory in various ways (and does not work as source to debug the Test.jar). I have tried running the directory listing test and hovering over variables, but they all work ok for me. Is this the source you intended to be in the jar file?
Regards,
Oliver

Oliver Deakin resolved HARMONY-6246.
------------------------------------
Resolution: Fixed
In ObjectReference.cpp we were not handling array type references correctly - fix applied at repo revision r798830. The test now passes for me in Eclipse where previously it crashed 100%. Please verify the bug has been fixed.

---------------------------------
Hi Hristo,
Thanks for your info of reproducing the problem. It would be helpful to diagnose the issue if you can upload the archive here which you are debugging. According to your description above, I suspect it was more likely a JDWP problem. The current code base of JDWP is a bit out of date and we have solved many defects in Harmony 6.0 JDWP which will be committed soon as Jimmy mentioned above. Anyway, will try your tests to investigate first : )

I have recreated this failure now in Eclipse - steps to reproduce are:
1) Launch test in Eclipse with breakpoint at line 102 of Test.java.
2) Expand the "packages" variable in the variable view.
3) Click on the "Show Logical Structure" button.

I have tested with the newly updated JDWP in the Java 6 branch and the failure does not occur there. Im going to have a look at ObjectReference::InvokeMethodHandler::Execute for the DeleteGlobalRef() call and see if I can find out what is going wrong.

[jira] Commented: (HARMONY-6246) Crash during debugging session

Hi,
The crash happens almost every time when I step through the code.
The steps to reproduce this issue:
1) start a program with added debug VM options (-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8888)
2) connect with IDE to the suspended process
3) stop at some point of the code (i have a break point almost at the beggining of the code)
4) "step over" several times
5) hold my cursor over some variable to see its value
Stepping through the code seems to be no problem. The crash always happens when I want to see the value of a variable (step 5)
I can provide the archive which I'm debugging as well the exact version of the IDE.
Btw on the IDE side I have a bundled SunVM:
java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Client VM (build 11.2-b01, mixed mode, sharing)
Can this be the reason for the crash?

----------------------------------------
Unfortunately I am still unable to recreate the failure in Eclipse using the new test case. The steps I followed were:
1) Set a breakpoint at the first line of main().
2) Step over and then into readPackageIndex().
3) Try random steps inside this method, or resuming to a breakpoint later in the method.
4) Hover over to get a value popup and expand various variables in the variable view (including expanding the LinkedHashSet "packages").
This all appears to work well for me, although I am running the test on the same machine I am debugging on. The next thing I will try is running on a remote machine and debugging locally, and if that does not fail I will try and set up IDEA and see if I can recreate there.
