Java(TM) Platform SE binary stop working Issue

[memoryfraction]

Some times, I met "Java(TM) Platform SE binary stop working " error. And TWS stop working , then communication failed too. This happens every 1-3 days.

log is attached at that day. Can Update JRE fix this issue? IBC-3.6.0_TWS-963_THURSDAY.zip

The log file shows that you want IBC to shut down TWS at 16:20 on Thursday, so presumably you have

ClosedownAt=Thursday 16:20

in your config.ini (with Thursday expressed in the Unicode equivalent for the Chinese characters).

But when 16:20 is reached, there are the following log entries:

2018-05-31 16:20:00:556 IBC: Getting main window 2018-05-31 16:20:00:764 IBC: Creating main window future

What's happening here is that IBC is trying to initiate the tidy shutdown, but it's unable to do anything on the UI thread: the only reason I know of for this is that you have a modal dialog on display, for example from Help > About Trader Workstation... Modal dialogs like this prevent access to the menu entries, so IBC is unable to do the tidy shutdown.

To avoid this issue, make sure you don't have any such modal dialog showing at shutdown time.

A similar problem occurs if you are running TWS with a non-English language setting, eg Simplified Chinese: if you do this, all the menu entries are also in Chinese, and IBC is unable to locate the required menu items, since it only 'speaks' English. I realise that might be unsatisfactory for those whose preferred language is not English, but there simply isn't the effort available to internationalise IBC so that it works with every language version of TWS.

Note that it's only TWS that you have to run in English: you can set your operating system language to anything you like.

Appreciate your help. First, TWS is running in English now. Second, about your assumption, I guess it's below dialog blocks the tidy shut down;

Next , I am going to fix above issue and see what happens next;

Yes, I think that would certainly block the tidy shutdown.

This message is probably caused by you installing a later version of TWS (say 972) and then reverting back to an earlier version (eg 963).

I suspect, but I'm not sure, that if you clear the 'Enable DDE Clients' API setting, TWS won't try to use the ddedll.dll file at all and the message won't occur. Of course, if you need Excel integration then you'll have to resolve the issue. Probably the way to do this is to uninstall all versions of TWS, and then just reinstall the version you actually want to target.
