Comment 2 NukemBy 2012-08-17 12:14:10 UTC

I've got this error during background scan of my project - so it may happen at any time.

I've debugged IDE a bit and it seems root cause for that problem is one of JSON files in my project which is not 100% sure JSON - it has at least comments inside it, what is successfully handled by Jackson parser with special configuration, but is not handled by nashorn library used in NetBeans 7.2.

Sample file to play with during debugging:

{
    "properties" : {
        // to be defined
    }
}

Comment 3 Vladimir Riha 2012-08-17 12:41:15 UTC

Yes, invalid json (like below) triggers this error


Sample file:
/* 
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

{
    "name": "vriha",
    "aasa":[1,1],
    "adresa":{
        
    }
}

Comment 4 NukemBy 2012-08-17 13:08:44 UTC

And one more strange thing - error report continues to pop up even after the project with the bogus json file is closed, i.e. I do "Project Context Menu -> Project Group -> (none)", create blank new project ... and, after some period, get the same error having only blank project being open in IDE. It looks like projects file cache is not cleaned correctly and obsolete items are being rescanned over and over again.

This is not the root cause for that particular problem, but can be a reason for performance and memory usage issues.
