Memory leak with SWT browser [message #748769]

Hello all,

I've developped an application based on the SWT browser widget which help Myspace browsing. Problem I have is due to known memory leak with SWT browser (either IE or Webkit).

bugs.eclipse.org/bugs/show_bug.cgi?id=134646

As my browser is alway open, memory leak tend to crash the app once javaw process reach approx. 900Mb (higher with a 64bits JRE).

I've tried several workaround with no success. Memory is growing every time a browser.setUrl() or a browser.refresh() is invoked.

Any news on this (old) bug ?

PS : by the way I think I have this problem since 3.7

Is your Browser ever disposed? The referenced memory leak is a problem
where not all memory that is allocated during a control's lifetime is
reclaimed when it's disposed. It's not a leak if the Browser is never
disposed though, because it is maintaining its navigation history.
Periodically disposing the Browser will reclaim some of this memory
(though some is known to leak).

Beyond this there's no further news. It's believed to be a problem in
the embedded IE control.

Hello,

Thanks for the answer !

The problem I have is that I never dispose my browser so the browser keeps growing and growing. The problem is mostly when using the setUrl() method. If i'm using the browser to navigate directly (by clicking inside the browser) there is no leak !

As far as I have tested, disposing the browser doesn't reclaim any memory at all.

Also the problem is worst since I've upgraded to 3.7 and IE9 compatibility.

Update : I've discovered that I can almost remove the memory leak problem with :

browser.setJavascriptEnabled(false);

However, some pages doesn't work this way... :-\
