Here are some examples of new versus old stacktrace.
"!" means the frame was in the java exception stacktrace, but are no longer present because the exception was caught

Well, I've gone and made an attempt at a "less leaky" version. (It became an obsession :( )
Some features:
- tries not to show internals of swank and abcl debugging calls
- shows top of exception trace for java exceptions, marked with "!" to
indicate they were caught.
- names local functions, even if we only would see the java frame.
- And some other nuisances. Read the code?
I am soliciting beta testers - need to see whether it holds up under stress of use by other. You will need to check out my branch of ABCL https://github.com/ alanruttenberg/abcl.git - use branch "stage" and you will need my branch of slime https://github.com/ alanruttenberg/slime/ - use branch "beta"
Build abcl with: ant abcl-aio.jar
There are a number of other debugging goodies here, also worth testing:
- Better inspectors for some things, like java classes
- View source and disassemble from debugger should work on every frame
- Most definition sources are recorded, including those compiled in a
buffer. Try edit definitions 'print-object and you will see all the methods and their source locations
- slime-edit-callers

I'm getting backtraces that are noisy and therefore impede
comprehension.
For example, in the following stack trace, frames 68-4 seem to recapitulate, for the most part, the java stack corresponding to frames 87-69
The ABCL backtrace abstraction is perhaps a little bit leaky and noisy with respect to its representation of Java calls, but it has been useful in improving the implementation in its present form since Tobias and I introduced it back in 2006-7 (?).
My strong claim is that a user of ABCL never will see Java calls in the backtrace, as they only result in errors in the ABCL implementation which causes the "Lisp computation" to fail, thunking out into the surrounding Java Try/Catch/Exception mechanism. So, "normally" (i.e. when there are more bugs in your code than the implementation), these verbose, confusing messages are not seen by the user.
In your example, frames 87-69 show the Lisp-side computation which got to the error being signaled in the ABCL implmentation. Then frames 4-68 provide the trace of Java attempting to deal with the error signaled by the JVM when executing Primitives.java:2845. Frames 0-2 show the error propagating back into the Lisp-side debugger machinery.
I think the only real information I get as a developer here is that there is an error occuring in org.armedbear.lisp.Primitives:2845; the rest of the Java calls don't need to be shown. The backtrace from 4-67 can confirm/deny hypothesis about what exacly caused the Java error on that line, but usually I would figure things out by starting ABCL under JPDA, setting a break point before Primitives:2845, replicating the error, and single-stepping through the JVM execution until I understand the problem.
The "logic" of javaPushStackFrames() (my code) is trying to elide noisy frames. Here it fails to elide frames in your example, as the entry point is in Primitive.java not Primitives.java, so this code should be changed. I would go with a simpler implementation of javaPushStackFrames() that doesn't try to elide frames, and place such a mechanism on actually viewing the stack. Perhaps we can get SLIME to "collapse" the Java portion of the backtrace (ala "the inspector") into a single statement of the source location that the Lisp computation enter the JVM error condition?
Hopefully that provides some background for a proposal for a less noisy backtrace for your purposes to be possible. Since I often get bug reports consisting of little or more reproduction instructions than: "I have a problem with ABCL: it gave me this error." and a paste of the stack trace, it has been useful to have more information present than not.
One could certainly somehow collapse frames 0-3 somehow into a single frame that represents the debugger invocation.
Thanks, Alan
