Description Jaroslav Tulach 2010-04-21 13:28:44 UTC
I have troubles debugging libraries without associated sources. I know how to workaround the problem, but the behavior is so clumsy that it deserves a bug report, imho.

1. take any project that uses an external library (just a JAR without sources)
2. checkout sources of the library (in my case a maven project, but it does not matter)
3. put a breakpoint into some source in the library
4. debug your project

The breakpoint in the library works and the execution stops there (good). The file is open in editor and program counter is highlighted (good).

Now press F8. One would expect the execution stops on the next line following the breakpoint but it does not! It goes on.

Workaround: Whenever I notice this (mis)behavior I locate the root of the sources, and add it into the debugging/sources window. However this UI gestures for doing so are really poor and long. Not talking about newcomers that are unlikely to find them at all.

Wish: Whenever a breakpoint is hit, make sure (automatically or via user hint) its source root is added (temporarily?) into the sources list.

If debugger opens the file and the current line is highlighted after stopping on breakpoint, then Step Over should just continue working with that file. Similar to bug 181305.
Comment 2 Ondrej Langr 2010-04-22 15:15:11 UTC
Agree that expected behavior is to continue on the next line. 

Jarda, why do you actually need to add the library into sourceroot in such case? Is it just a workaround to be able to debug such file or do you need it for the future too .. ?
Comment 3 Jaroslav Tulach 2010-04-23 09:53:33 UTC
As a user I don't care about source roots, I just want to debug the library I have breakpoint in. The "debug" here however means various combinations of F8, F7, F4 in the class with the breakpoint as well as in other classes in the same library.

Fixed in changeset:   172881:f98a44c11fbe

When you try to step into an unknown source, it's source root is automatically added into the Sources tab. This resolves this problem.
