Has MyEclipse implicit breakpoint in debugging mode in class URLClassPath

Question

I am beginner in MyEclipse IDEA. I using 8.6.1 version of it. My issue is: When I execute my program in debug mode, MyEclipse go to sun.misc.URLClassPath class and I must Resume breakpoint(by pressing F8 key) and continue executing my program. MyEclipse stay in URLClassPath class in following thread stack:

1. URLClassPath$JarLoader.<init>(URL, URLStreamHandler, HashMap) line: 581  
2. URLClassPath$JarLoader.ensureOpen() line: 631    
3. URLClassPath$JarLoader.getJarFile(URL) line: 641 
4. URLClassPath$JarLoader.ensureOpen() line: 631    

Note: this event happen when some jar file exist in my project Build-Path but when my application is simple this problem don't make and first breakpoint is my first breakpoint.

Why this event happened?

Answer 1

I've reproduced the error and it is not possible to debug the application. The only way that I've found to fix this issue has been: go to "window->Preferences->Java->Debug" and disable the "suspend execution of uncaught exceptions"

Now is possible to debug the application and the debugger stops in the user breakpoints.
