[Wrapper-user] jni multi-threaded issues

[<kri...@st...>]

Hello,

First of all it might be worth saying that my application works perfectly fine
without the wrapper. I am using a dll that maintains a state depending on
various calls (this dll actually automates an office app). 
Trying to make calls in a one threaded application works, the problem arises
when I have multiple threads. One simple test I made is letting one thread run
the init method in my dll, then letting the shutdown hook run the exit. When
making that call the jvm crashes:

#  Internal Error (0xe06d7363), pid=232, tid=2960
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0_01-b08 mixed mode, sharing)
# Problematic frame:
# C  [kernel32.dll+0xd756]

looking at the stack I can see

Stack: [0x031f0000,0x03230000),  sp=0x0322f8f4,  free space=254k
Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code)
C  [kernel32.dll+0xd756]
C  [MYOWN.dll+0x7a2b]
...
J last java call made

current thread is marked as being in native.

I am clueless about what to do. Any ideas of what causes this problem when
runnin in the wrapper would be very appreciated!
