Apex Listener oci8

Hello everybody,

I've got the following error message after starting apex listener standalone if I try to use oci8 instead of  thin (<entry key="jdbc.DriverType">oci8</entry>) in defaults.xml-file:

# A fatal error has been detected by the Java Runtime Environment:

#

#  SIGSEGV (0xb) at pc=0x00002acbc25f16d4, pid=20371, tid=47054636099904

# JRE version: 6.0_45-b06

# Java VM: Java HotSpot(TM) 64-Bit Server VM (20.45-b01 mixed mode linux-amd64 compressed oops)

# Problematic frame:

# V  [libjvm.so+0x5176d4]  unsigned+0xd4

Has anybody somes ideas why ?

TIA.
