If you are using multiple bluetooth dongles and multiple instances of a java
application, you should share the libbluecove between the applications, putting the
library in a directory '/home/myuser/libbluecove' and pass the following arguments to
the jvm:
java -Dbluecove.native.resource=false -Dbluecove.native.path=/home/myuser/libbluecove
-Xshare:off -jar myApplication.jar

This will stop generate the error_pid.log.

We are trying to run example program "RemoteDeviceDiscovery" under Voyage Linux
(which is based upon Debian).

java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)

The file was compilated with Netbeans 6.1 and runs under Windows. But unfortunatly we
run into the same problem as described at the beginning by execute the following
statements:

java -cp lib/bluecove-2.1.0.jar:lib/bluecove-gpl-2.1.0.jar -jar
RemoteDeviceDiscovery.jar main

or 

java -cp lib -Dbluecove.native.resource=false -Xshare:off
-Dbluecove.native.path=/daten/bluecove/ -jar RemoteDeviceDiscovery.jar

or

java -cp lib/bluecove-2.1.0.jar:lib/bluecove-gpl-2.1.0.jar -jar
RemoteDeviceDiscovery.jar main



Here is the console output:

#
# An unexpected error has been detected by Java Runtime Environment:
#
#  SIGFPE (0x8) at pc=0xb7f73745, pid=23084, tid=3084831664

Have you tried Obvious, compile bluecove.so on your platform?
