java - JavaFX error when ending Swing application -


i have swing application in need display internally generated html/css. in order this, have adapted the code stackoverflow question.

the control works fine. however, when application ends, receive error

# # fatal error has been detected java runtime environment: # #  sigsegv (0xb) @ pc=0x00007f9622171ae8, pid=5782, tid=140283095549696

for it's worth, sample code directly oracle (quoted in stackoverflow post) has same problem.

i have tried explicitly calling platform.exit() when window closes, error remains. so, how 1 shut down javafx correctly, when embedded in swing application?

ok, found solution, @ least application:

  • this multi-window application; javafx component not in main application window, in sub-window.

  • the javafx "platform" has setting "implicitexit", default "true".

  • javafx platform.exit() apparently called both when sub-window closed, , when main application closed. second call (when application closed) generates error message described in original question.

  • the "implicit exit" behavior in case undesirable, because prevents sub-window being re-opened second time during application's lifetime.

hence, solution turn off "implicit exit". here's javafx initialization code in subwindow:

platform.runlater(new runnable() {     @override public void run() {         view = new webview();         engine = view.getengine();         jfxpanel.setscene(new scene(view));         platform.setimplicitexit(false); // otherwise cannot open report window second time     } });

assembly - 8086 TASM: Illegal Indexing Mode -

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
