JDB stops on every exception - how to prevent this

Question

I am using a jdb dubugger, and the problem with it that is stops on every caught exception, though I did not execute any catch .... statements. During class loading there are hundreds of them:

Exception occurred: java.io.FileNotFoundException (uncaught)"thread=Thread-2-EmulatorEngine", sun.misc.URLClassPath$JarLoader.ensureOpen(), line=634 bci=30

Is it any way to instruct jdb to skip these exceptions ?

PS. I have heard about IDE editors of cause. Have reasons to use jdb.

Typically it only does this if the exception isn't going to be caught, so java is going to exit otherwise. These are exceptions that are caught somewhere? — Michael Mrozek, Jul 03 '12 at 14:20

I realized that I am not careful enough. JDB writes after launch these lines

Set uncaught java.lang.Throwable

Set deferred uncaught java.lang.Throwable

So, to disable that, I need to enter a command

ignore uncaught java.lang.Throwable

Not found: uncaught java.lang.Throwable Usage: ignore [uncaught|caught|all] | When running jdb App.class, would anybody have any ideas? – 64k Aug 05 '17 at 22:40

If you're having the same issue as me, you need to use the fully qualified name of the class when defining the break point.

Example - Set break point in main method: stop in com.foo.bar.App.main

It may be that you are trying to set a break point for a class file different than the one you are debugging (which probably doesn't exist).
