Hi,
I am using FreeBsd 3.4 with jdk 1.1.8 green threads on i386 . I
am getting Segmentation violation from JNI call as reported in PR
12286.
Program is crashing when I try to create a new Java object
using JNI NewObject function. Problem report still says that bug is
open. The PR is included in the end of this mail.
Any one of you know the solution for this problem or have a patch for
this problem.

Description
When I link a static library which calls pthread routines into a
shared object file with gcc -shared -pthread, and then run the
java compiled program which calls it through JNI with JDK 1.1.8
(green threads), (I had to add -lc_r to the link flags in order
to get pthread_mutex_lock() to be found when linking the .so file),
I get the following Segmentation violation:
(cd jni; java pntransjava test.paymentnet.com 443
"TRXTYPE=S&TENDER=C&PWD=g0edel
1685&USER=pnprodtest&ACCT=5105105105105100&EXPDATE=1299&AMT=27.33"
30; cd ..)
