Method::_vtable_index is positive and holder is interface. Looks incorrect: (gdb) bt #0 0x00007fdc640aa619 in __libc_waitpid (pid=32420, stat_loc=0x7fdc647c2ea8, options=0) at ../sysdeps/unix/sysv/linux/waitpid.c:40 #1 0x00007fdc62f705d8 in os::fork_and_exec (cmd=0x7fdc63baf500 <VMError::report_and_die()::buffer> "gdb /proc/32404/exe 32404") at /home/lev/code/jdk9/dev/hotspot/src/os/linux/vm/os_linux.cpp:5924 #2 0x00007fdc6318dbd9 in VMError::show_message_box (this=0x7fdc647c31b0, buf=0x7fdc63baf500 <VMError::report_and_die()::buffer> "gdb /proc/32404/exe 32404", buflen=2000) at /home/lev/code/jdk9/dev/hotspot/src/os/linux/vm/vmError_linux.cpp:60 #3 0x00007fdc6318c77a in VMError::report_and_die (this=0x7fdc647c31b0) at /home/lev/code/jdk9/dev/hotspot/src/share/vm/utilities/vmError.cpp:883 #4 0x00007fdc62994b80 in report_vm_error (file=0x7fdc632e7dc0 "/home/lev/code/jdk9/dev/hotspot/src/share/vm/oops/method.hpp", line=459, error_msg=0x7fdc632e7e00 "assert(valid_itable_index()) failed", detail_msg=0x7fdc632e7d9d "") at /home/lev/code/jdk9/dev/hotspot/src/share/vm/utilities/debug.cpp:217 #5 0x00007fdc6292bbfe in Method::itable_index (this=0x7fdc4c83d5d8) at /home/lev/code/jdk9/dev/hotspot/src/share/vm/oops/method.hpp:459 #6 0x00007fdc62c8607a in jni_invoke_nonstatic (env=0x7fdc5c00fa38, result=0x7fdc647c3500, receiver=0x7fdc5c0fa078, call_type=JNI_VIRTUAL, method_id=0x7fdc5c198e68, args=0x7fdc647c3530, __the_thread__=0x7fdc5c00f800) at /home/lev/code/jdk9/dev/hotspot/src/share/vm/prims/jni.cpp:1153 #7 0x00007fdc62c8b9ae in jni_CallObjectMethodV(JNIEnv *, jobject, jmethodID, typedef __va_list_tag __va_list_tag *) (env=0x7fdc5c00fa38, obj=0x7fdc5c0fa078, methodID=0x7fdc5c198e68, args=0x7fdc647c3608) at /home/lev/code/jdk9/dev/hotspot/src/share/vm/prims/jni.cpp:1483 #8 0x00007fdc3e7b273c in JNIEnv_::CallObjectMethodV (this=0x7fdc5c00fa38, obj=0x7fdc5c0fa078, methodID=0x7fdc5c198e68, args=0x7fdc647c3608) at /home/lev/Downloads/8u20x64/include/jni.h:907 #9 0x00007fdc3e7b1ddf in callStringMethod (env=0x7fdc5c00fa38, jobj=0x7fdc5c0fa078, id=0x7fdc5c198e68) at Test.cpp:17 #10 0x00007fdc3e7b24bc in Java_test_Test_nTest (env=0x7fdc5c00fa38, jobj=0x7fdc647c37d0) at Test.cpp:113 #11 0x00007fdc4d0281bf in ??

this decision http://hg.openjdk.java.net/jdk9/dev/hotspot/file/e0947f58c9c1/src/share/vm/prims/jni.cpp#l1126 goes to else branch before crash. Look like bug is somewhere while getting wrong jmethodID while resolving it through jni_CallObjectMethodV .
