gcj v4.8.3 on Cygwin

Hello,

my problem is that : I like compile/link jar files into native exe for 
Windows with the nex command line:

gcj -fjni  --main=com.all.alldio.dlr.main.StarterClass ./Jars/sndsep.jar 
./Jars/alldioutil.jar ./Jars/alldio_d2014_moreAM.jar -o diktalo.exe

but the gcj return an Segmentation fault message. I do not understand that 
why, because the next command line generates the required exe file

gcj --main=com.all.onins.oi.OnlineInputStub ./Jars/sndsep.jar ./Jars/sns.jar 
./Jars/smws.jar ./Jars/onins.jar -o onins.exe

please help me any words.

best regards
