找到了一些简介.

就是因为,其它的项目有的断点.把那些断点去掉就可以了.

This is a follow-up to the posting "Unexpected breakpoint in debugger". I

didn't find a bug report as was suggested in the posting.

When I run my program normally, everything is fine. But when I run in the

debugger, I get the error below. I've tried changing the option with no

effect: Window>Preferences>Java>Debug>Suspend execution on uncaught

exceptions

The problem seems to happen in cases where a class is instantiated from

another branch in the source tree or in a different project or from a jar.

It works if all the classes are in the same project and location.

Setup:

Eclipse 3.2.0 using JRE 1.4.2

Windows XP Pro

Has anyone else run into this?

Thanks,

Keith

原回答如下:

In the Breakpoints view, do you see any listed? Use the "XX" button to

remove all breakpoints - it is possible you inadvertently created an

Exception breakpoint, which will break any time the exception is thrown.

Hope this helps,

Eric

后来这个发贴人说问题解决了.回复如下.

Yes, clearning out the Breakpoints worked, Thanks!

然后我试了下,果然如此.真是太高兴了.

要知道,我也折腾了很久啊..
