In Java_jdk_internal_org_jline_terminal_impl_jna_linux_CLibraryImpl_tcgetattr a field is accessed incorrectly from JNI.

  data.c_line = env->GetIntField(input, c_line);
  env->SetIntField(result, c_line, data.c_line);

But the c_line field is a byte field e.g. c_line = env->GetFieldID(termios_j, "c_line", "B");

This was detected by Espresso (alternative JVM implementation) which is strict on the fields types when accessed via JNI.
