RE: [Swarm-Support] Error running swarm in Windows: JVM access vi olation

[Marshall, James A R]

Otto,
  have you tried running your model through jdb (the Java debugger) yet?
This could help you work out what's causing the problem. So, you're using
the same JDK and same version of Swarm on both machines? It seems strange to
me then that the same code should run on one and not the other... you say
you're using XP on both machines too? Try comparins service packs.
  Anyway, the main thing to do is use jdb and see where in your code the
problem is triggered.
        James

Hi all,

I changed my jsdk to 1.4.1 version but the error is still ocurring. This is
the message I get when trying to run any swarm application in my win-xp,
j2sdk 1.4.x, swarm 2.1.1.

*** event raised for error: InvalidArgument
*** function: _i_Object_s__forward__(), file:
/src/Swarm/swarm/src/defobj/DefObj
ect.m, line: 626
unable to find Java selector `allocIVars:' in objc:`JavaProxy' 0x1098db58
java:
0x9aa0bc hash: 14078
*** execution terminating due to error
/src/Swarm/swarm/src/defobj/Symbol.m:173 -[Error(c) _raiseEvent:]
      0 [sig] java 1000 stackdump: Dumping stack trace to java.exe.stackdump

The stackdump is below in this email, but I think it doesn't say much.
Can someone please help me with this?, do you know how can I solve this
error?

Thanks,

Otto.
