Hello Laurent,

I would have no idea if the performance is impacted or not by using that 
flag permanently. If you always have access to the first time the same 
exception was thrown at the same place, it's no problem and wouldn't be 
worth the hassle. I think if you want to put it somewhere, it would be in a 
lein profile so you'd have it in development, but not in production.

Regards,

Niels

Hello Niels,

that's interesting. Would it deserve that CCW adds this option
automatically when asked to start a REPL ? I could probably easily do this
in both cases : when the REPL start is delegated to Leiningen, or when the
REPL is created by ccw by using whatever is in the project's java build
path.

Do you know if there would be e.g. performance impacts that would be
annoying for certain kinds of projects?

I'm sure first thing in the morning there'll be someone at Larry Ellison's 
door clamoring for removal of hotspot optimization from the JVM..

The first result of googling

jvm "[trace missing]"

is really helpful here.

It's a giant pain to debug exceptions without stack traces. This seems 
to be a problem specific to CCW, as I don't encounter it using other 
development environments.


Is this going to be fixed anytime soon?

Re: Getting sick and tired of "[trace missing]"

This isn't a CCW exclusive issue, but the Oracle JVM 'optimizing away' 
stacktraces.

It can be remedied by adding the '-XX:-OmitStackTraceInFastThrow' flag to 
the JVM startup parameters of the process you're starting.
If Leiningen is used to start the JVM, add the following setting to your 
lein project.clj map:


:jvm-opts ^:replace ["-XX:-OmitStackTraceInFastThrow"]

Oh, and you're welcome..

Pseudonymous obnoxious person:

You have many options.

(a) Submit a (polite) issue to the CCW tracker with sufficient information
to reproduce the behavior. If an issue already exists, comment (politely)
on the issue to register that it's one toward which you would like the
project's volunteers to consider allocating their efforts.

(b) If the issue is of sufficient importance to you, offer a bounty
(payable in actual money) for an implementation of your desired behavior.
If you ask (politely), someone may be willing to implement it for you in
exchange for cash.

(c) Determine the source of the undesired behavior and implement a fix
yourself. I'd suspect the project's maintainers would happily entertain
a pull request. If you do not have sufficient knowledge to understand
how to approach an implementation, others may be willing to guide you if
you ask. Politely.

(d) Stop whinging and use the free software.

(e) Stop whinging and don't use the free software.

(f) Take your whinging somewhere else.

Moderators:

Many, many people sincerely attempted to help this person during the last
round of self-obsessed, abusive entitlement. May I request that you step in
if it looks like this thread is going down the same path?

I do not wish this community to become one that tolerates incivility.

Thanks to all of those on this list and behind the scenes who work to
support this great programming language, its tooling, and the vibrant
ecosystem of libraries.

Getting sick and tired of "[trace missing]"

[Fluid Dynamics]

It's a giant pain to debug exceptions without stack traces. This seems to 
be a problem specific to CCW, as I don't encounter it using other 
development environments.

Is this going to be fixed anytime soon?
