Description Yuri Magrisso

2003-04-05 07:01:29 EST

When I initiate a remote debug session against Sun's WTK 2.0 (with the -Xverbose
flag) I receive the following error message:
zayit.exe - Application Error <window title>
The instruction at "0x0000000a" referenced memory at "0x0000000a". The memory
could not be "read".

When I initiate it without this flag the message reads:
zayit.exe - Application Error <window title>
The instruction at "0x0042a9fa" referenced memory at "0x0000001c". The memory
could not be "read".

I receive similar error messages when I use WTK 1.0.4, or Eclipse 2.0.2.
The MIDlet that I try to debug is a "Hello World" application.

The jar/jad files are created with antenna 0.9.8 (http://antenna.sourceforge.net)

Except for the antenna debug target, I have attached 3 debug batch files and
their corresponding output logs (debug.bat >> debug.log, debug1.bat >>
debug1.log, etc.). The output of the antenna debug target is the same as in
debug2.log.

For any questions write to yumariso@fastmail.fm.

Regards,
Yuri Magrisso

Copy of dos output - launch demo in debug mode

I have the same problem (eclipse 2.1 - win nt - 1.4.1-rc).
I launch the demo apps of J2ME-WTK2.0 using the following modified .bat.
The attachment is the output of that .bat.

rem Modified run.bat  to debug demo apps
set PROJBINDIR=..\apps\demos\bin
@echo on
cd ..\..\..\bin
emulator  -Xverbose:all -Xdebug
-Xrunjdwp:transport=dt_socket,address=5000,server=y -classpath
%PROJBINDIR%\demos.jar -Xdescriptor:%PROJBINDIR%\demos.jad
cd %PROJBINDIR%

Going with "not our bug" on this one.

We just connect to the WTK following the JDWP protocol standard. If the VM 
crashes in response to this, it's pretty clear that this is a problem with the 
KVM.

I suggest opening a bug report against the WTK vendor.
