Node.js exited abnormally: java.lang.IllegalArgumentException - Null stream!

[gavinking]

On Mac, with node v0.10.13, and Ceylon IDE from git, I get the following attempting to Run As > Ceylon JavaScript Application:

!MESSAGE Node.js exited abnormally: java.lang.IllegalArgumentException - Null stream!

Note: the js files are correctly produced in the modules dir.

[gavinking]

I have reproduced this using the latest dev build of the IDE from the development update site.

[gavinking]

FTR I also get this error from the M5 IDE release.

[chochos]

This seems to be caused by problems with the js part of the IDE, however it would be useful to get a more informative message from the CMR when asking for nonexistent artifacts...

[gavinking]

So the IDE side of things now seems to be essentially fixed, but we need to make sure that CMR never behaves like this.

[alesj]

What exactly is the problem? Or what's causing this null stream?

Or are you just saying CMR should give better error msg?

[gavinking]

If I understand the stack correctly, CMR was trying to cache something that wasn't even in Herd. Had something to do with the list of repo's being in the wrong order.

[gavinking]

It might be something that happens when remote repos occur before local repos in the list.

[alesj]

Uh, again repo order ... @FroMage, @quintesse ... I thought we had this fixed.

Can we get a test that reproduces this?

[gavinking]

It looks like we've got the repo order approximately fixed in the IDE JS runner, but the point is that CMR simply shouldn't die in this manner, with what is essentially an npe.

[alesj]

Yes and no. Something is trying to push null stream, which is what CMR complains. It shouldn't get as far as to trying to push null stream. That's what we need to find, what's responsible for pushing this null stream.

[gavinking]

That's what we need to find, what's responsible for pushing this null stream.

I think it's the caching stuff.

[alesj]

I think it's the caching stuff.

Any chance to create a test which reproduces this?

[FroMage]

Added a more helpful error message and moving to 1.0

[gavinking]

I'm not sure if that's good enough. I need to recheck, but I believe that right now I can't run any JS app on Mac.

[FroMage]

OK, well try it and let me know. I still don't know what's causing this but the new error message should help.

this is the error i get from windows environment

[DiegoCoronel]

Ok, just ignore my case above, it worked.. it was because json dependency.. its working fine for me in windows.

[FroMage]

This is now fixed!
