Description soldatov 2008-02-04 11:02:22 UTC
I installed full Netbeans nightly build (with all packs). And I have such problem:
1)create new netbeans plug in module project (standalone, with default settings)
2)run it (F6)
3)close the appeared IDE
4)run it again
==> exceptions

Comment 2 Lukas Hasik 2008-02-04 12:48:59 UTC
seems as wrong project setting -> passing to apisupport for evaluation
Comment 3 Petr Nejedly 2008-02-04 13:12:47 UTC
No, not really. More probably a problem with module system caches.
Comment 4 Jaroslav Tulach 2008-02-05 08:37:47 UTC
Nejedlák is probably right.
Comment 5 Jesse Glick 2008-02-05 19:55:55 UTC
A duplicate, I believe.

Comment 7 Jaroslav Tulach 2008-02-11 15:57:09 UTC
Nejedláku, I believe this is a bug in your code. If one uses testing modules, then 

      Source _src = Source.sources.get(jar);

in JarClassLoader can yield null. Is that a bug, do how would you fix it?
Comment 8 Petr Nejedly 2008-02-11 17:41:40 UTC
If I understand it correctly, the subsequent start (or is it reload inside an already running IDE) uses some kind of
cached URL to a file which is either no longer there, or whose class loader was destroyed.
Either way, the system should claim that there's no such resource.

It might have claimed that the resource exists (i.e. getResource returned well-formed URL into (nonexistent) jar)
because the cache have contained an entry for given file (it was there on the first start).
I would probably disable the cache if there are testing modules somehow.

Comment 12 Jiri Skrivanek 2008-02-19 10:06:28 UTC
Exception is fixed but module is loaded just once and it is not reloaded anymore. To reproduce:

- create new netbeans plug in module project (standalone, with default settings)
- add some action to main menu
- run module (F6)
- check action is there
- add one more action to main menu
- run module (F6) but the second action doesn't appear in main menu. It behaves similarly if you call 'Reload in
Development IDE'.
