0x7f6551c27290 is a signal handler frame, and its caller is native frame. However jstack reports the caller is Java frame (NativeSEGV.doSEGV()).

It should be like following:

0x00007fdbd170321a JVM_handle_linux_signal + 0x42a
0x00007fdbd267b290 <signal handler called>
0x00007fdbc7ecb3b1 Java_NativeSEGV_doSEGV + 0x18
0x00007fdbb67468ba * NativeSEGV.doSEGV() bci:0 (Interpreted frame)

This is long standing bug (since JDK 9 at least).
