(code 1): toastbar.java, line 602

c.label.getparent().replaceandwait(c.label, newlabel, commontransitions.createcover(commontransitions.slide_vertical, true, 300));

(code 2): digitroller.java

protected void copytoclipboard () {         clipboard.copystring(stoken);         toastbar.showerrormessage("copied " + stoken, 1000);     }

copytoclipboard() invoked actionlistener:

btncopy.addactionlistener((e)-> {             this.copytoclipboard();         });

after displaying exception details in dialog app freezes or stops animations it's own decision. extremely simple way crash application.

this seems bug, added potential workaround here.

Sockets with kotlin -

i looking develop application in kotlin uses sockets, unfortunately kotlinx sockets broken , not far connect current kotlin 1.1 co-routines. (i see noted unanswered issue on github @sundwarf on july 16 already) specifically, sample code kotlinx.sockets uses connect in form: asocket().tcp().connect(inetsocketaddress(inetaddress.getbyname("google.com"), 80)) which fails noted trace here . i looking either sample of connect work, or recommendation of alternate package kotlix.sockets. there many kotlin apps making use of sockets, either there alternatives kotlinx.sockets or there way around connect problem.
