Pavel Pervov commented on HARMONY-4006:
---------------------------------------

The problem on Linux is in different TLS models used in eclipse launcher and harmony VM. Will
investigate further to find out the way to fix this.

> We would like for the eclipse launcher to be able to start the harmony vm using the JNI
invocation API.
> The eclipse launcher does not know anything about the port library.  It looks for the
symbol "JNI_CreateJavaVM" and calls it.  If we modify the eclipse launcher to find "_JNI_CreateJavaVM@12"
from the harmonyvm.dll, then the result is the following crash:
> Thread [1] (Suspended: Signal 'SIGSEGV' received. Description: Segmentation fault.) 
   
> 2 harmonyvm!?classloader_find_native@@YAP6AXXZQAUMethod@@@Z()  0x00a8ecd8       
> 1 <symbol is not available> 0x00000000
