android - Why parsing StackOverflowException throws OOM? -

-

i noticed, app users got error:

fatal exception: java.lang.outofmemoryerror: outofmemoryerror thrown while trying throw outofmemoryerror; no stack available

so, had written pretty simple app:

public class mainactivity extends appcompatactivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          log.d("tag", "" + getfoo());     }      private int getfoo() {         return getbar();     }      private int getbar() {         return getfoo();     } }

who throws oom while parsing stackoverflowexception not able stacktrace in log:

have idea how can fix oom or how stacktrace in prod?

update:

threadgroup group = new threadgroup("threadgroup"); new thread(group, new runnable() {     private void stackoverflow() {         stackoverflow();     }     @override     public void run() {         stackoverflow();     } }, "name", 20).start();
