Which other module?  Do we have access to it to try to reproduce the problem?  
What is test.rcp.RcpApplication?

Comment 2 Clara MUI 2004-10-18 23:00:56 EDT

The module is built in-house, which use another .jar named JIntegra. This 
package is to wrap the .dll and acts as a bridge to convert the APIs in .dll 
to java API. That module works fine if it is plugged with other pure java 
application which my team and I used to have. 

But not with eclipse plug-in. I tried to trace the problem and found that that 
when this module is loaded, the jintegra.jar will register some system 
libraries, and when it comes to initializing eclipse plug-in, and the line 

at org.eclipse.swt.dnd.DropTarget.<init>(DropTarget.java:135)

	if (COM.RegisterDragDrop( control.handle, iDropTarget.getAddress()) != 
COM.S_OK)
		DND.error(DND.ERROR_CANNOT_INIT_DROP);

It does not return COM.S_OK, but something like -214xxxxxx
And then the application quits.

I am not sure if you would like to get a trial version from http://j-
integra.intrinsyc.com. Include this package into the library path and set the 
java argument to -DJINTEGRA_NATIVE_MODE (which will load the system library)

FYI, I tried to workaround and initialized my packages after eclipse plug-in's 
(which is not what I want actually - I would like to initialize my packages, 
do the login, before loading GUI (eclipse plug-in)). Though the application 
successfully loaded, when I shutdown my application, it fails to clean up the 
jintegra package (which I am not sure if it's eclipse's plug-in again?)

test.rcp.RcpApplication is the testing application I used for eclipse plug-in.

Comment 3 Veronika Irvine 2004-10-21 15:35:03 EDT

Can you give the exact error returned by COM.RegisterDragDrop(you said -
214xxxxxx - but I need to know is the  exact error code)?

In your second scenario, can you include the full exception thrown by Display 
display = PlatformUI.createDisplay() ?

Comment 4 Clara MUI 2004-10-24 21:49:34 EDT

it returns -2147024882, instead of COM.S_OK (constant zero), and so the error 
thrown on line 
     DND.error(DND.ERROR_CANNOT_INIT_DROP)

to correct my previous statement, the exception should have been thrown on 
line (as shown in trace log)

     int returnCode = PlatformUI.createAndRunWorkbench(display,
                    workbenchAdvisor);

but not 
   Display display = PlatformUI.createDisplay();

Regarding the workaround I did, the exception was thrown from the JIntegra 
package, which was supposed to do some cleanup work on system libraries, 
again, it orginally works fine with pure java application, but when I plug-in 
the module with eclipse, so I am not sure if eclipse has worked on the same 
system libraries as JIntegra which makes the crashes

Comment 5 Veronika Irvine 2004-10-25 15:31:53 EDT

The error is "0x8007000E  -2147024882  Ran out of memory".  Do you start the 
VM with any memory size arguments?  e.g.:

      eclipse -vmargs -Xmx256M

Comment 6 Clara MUI 2004-10-25 23:50:13 EDT

yes. 

the eclipse starts with argument '-vmargs  -Xmx384m -Xms256m' and the 
application starts with argument '-Xms256M -Xmx256m'

is it 256m not enough ? but i run the application in pure java with just '-
Xms64M -Xmx64m' and everything works fine.

again, the line with error thrown is

at org.eclipse.swt.dnd.DropTarget.<init>(DropTarget.java:135)

	if (COM.RegisterDragDrop( control.handle, iDropTarget.getAddress()) != 
COM.S_OK)
		DND.error(DND.ERROR_CANNOT_INIT_DROP);

if i am correct, this line is to load/register the system library ? is it 
there is issue in loading system library at eclipse plug-in if that has been 
loaded by others in the same jvm process ?

fyi, the JIntegra does load some system libraries, but I don't know if eclipse 
plug-in crashes with those ? or brings to window's issue ?

Comment 7 Eugene Ostroukhov 2004-11-22 09:49:20 EST

Got same exception when our application was ran on a terminal server (W2000 
Terminal SP2). Application was tested on Windows XP and ASP linux (GTK) and 
this problem was never encountered. Our application is built on a RCP 3.0.

Comment 8 Jacek Pospychala 2007-06-27 12:28:39 EDT

Hello,
it's really long since the bug was last touched, but do you have any thoughts what could the root cause be?

Did it ever worked on terminal server?
Did it worked with any higher memory size values?

Comment 9 Duong Nguyen 2007-06-27 14:07:56 EDT

I don't have Terminal Server to reproduce this problem. Are you running into this problem now?

Comment 10 Jacek Pospychala 2007-07-26 10:53:27 EDT

no it wasn't on terminal connection. It was a one-time issue and doesn't occur any more.

Comment 11 Niraj Modi 2017-07-04 04:19:03 EDT

Closing, as WinXP is no longer a supported OS platform.
You can reopen this bug if it still happens with any of the current supported platforms with valid steps to reproduce this issue.
