RE: [Swarm-Support] Re: Problem of using SWARM under Eclipse, NetBeans

[Angela Johana Muñoz Idrobo]

Hi

We are from Colombia, We speak Spanish so sorry about possible mistakes in 
our English wrinting.

We are programming with Swarm 2.1.1 using NetBeans IDE , we think Swarm 
2.1.1 does not need cygwin so we compile and run our application from within 
NetBeans. We are not using the Control Panel to manage the simulation 
instead we use a interface that extends of JFrame. When we start the 
simulation clilcking in a JButton we create a object of HiloSimulacion 
class, this class extends of Thread class of java, and also we start this 
thread. In the run() method of the thread we call to Globals.env.initSwarm, 
we build the objects that needs the model, we build the actions, we active 
the model and finally we start the model`s activity with next() method. The 
first time we run our application, using NetBeans, everything is ok but when 
we run it again we got the following exception:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION (0xc0000005) occurred at 
PC=0x6104C688
Function=sem_post+0x90
Library=C:\Swarm-2.1.1\bin\cygwin1.dll
Current Java thread:
       at swarm.SwarmEnvironment.initSwarm(Native Method)
       at simulacion.HiloSimulacion.run(HiloSimulacion.java:53)

we attach to this email the error report file “hs_err_pid312.log”

What do you think about this problem? do you think it is necessary to move 
on to Swarm-2.2 to solve this exception? Please write us something, thanks a 
lot
