swt一个很妖怪的问题

Question

大家好：
    最近在做一个swt的项目。突然发现当窗口打开过多的时候，程序会死在那里，而且开发用的eclipse也会自动关闭。
想到过或许是内存泄漏，线程没跑完之类的问题，始终没个头绪。这方面有经验的达人们给点思路吧，谢谢

Answer 1

eclipse会有错误日志，检查一下就清楚了。另外，也可以调整eclipse的内存参数，加大内存，可能有帮助。

Answer 2

貌似是out of memory问题。

刚才查看了下错误日志，出现的最多的是：

这种信息，大家能帮着看看嘛？

Answer 4

大家说说看，是不是swt对窗口数量有限制，或者是创建了窗口，没有释放里面小部件的内存啊，急死了，大家帮帮忙丫，在线等

Answer 5

仅仅是你的menuitem没有create成功吧
你看看你createMenuitem的地方

Answer 6

菜单问题 不是swt的问题 ，
