Hi, I am trying to use Java scripting (JSR 223) with GCJ. To do that I tried compiling the scripting jar file that implements JSR 223 into a shared library and to use it in my app. However I always get a SIGSEGV in the init function of the shared library. As you can see (in the build.sh script) I tried all combinations of -findirect-dispatch and -fno-indirect-classes without success. Any help to get that running is highly appreciated. Thanks in advance! Lothar
