eclipse

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?
