Hi!

I have been trying to find some pointers about this warning in the forum, but couldn’t find anything. I see a few Javascript warning of the type: “Bad number: ‘='” upon my JS scripts. I have identified that they are displayed for the following type of scripts:

var MySomething = {
    myFunction = function() {
    }
}

The warning is reported on line 1, for the = sign. I am wondering what is the meaning of this warning message.

Environment:
MyEclipse 4.1.1
Eclipse 3.1.2
JVM: SUN 1.5.0_06 or JRockit 26.3.0-1.5.0_06

TIA,

I just copy and pasted this into a new test.js file and the <script> section of a new html file, and neither of them got marked with errors. Can you duplicate this on your end?

Can you paste an entire file where you have the error or a shortened version of it?

[Alexandru Popescu]

Here is one:

FCKConfig.ToolbarSets["ContentToolbar"] = [
        ['Cut','Copy','Paste','PasteText'],
        ['Undo','Redo','-','Bold','Italic','Underline','StrikeThrough'],
        ['OrderedList','UnorderedList','-','Outdent','Indent'],
        ['Link','Unlink','Anchor'],
        ['Image','Rule','SpecialChar', '-','Source']
] ;

FCKConfig.Debug = true ;
FCKConfig.LinkBrowser = false ;
FCKConfig.ImageBrowser = false ;
FCKConfig.ImageUpload = false ;

var CUSTOMLINK_PLUGIN_PATH = '/../../../';
FCKConfig.Plugins.Add( 'fckcustomlink', null, FCKConfig.BasePath + CUSTOMLINK_PLUGIN_PATH) ;

In the problems view:

Description: Bad number: ‘=’.
On resource: custom_fckeditor.js
Location: line 1

On the gutter I have a warn sign and the following message:
Multiple annotations found at this line:
– Bad number: ‘=’.
– 16 changed lines

Alex,
Right click on your project and go to MyEclipse > Remove All Validation Markers. Then rebuild your project… I can’t reproduce this problem.

Can you copy paste your result from MyEclipse > About > Configuration Summary for me?

Hmm. What happens ifyou switch to using the “javaw” executable from the Sun JDK and not JRockit?

[Alexandru Popescu]

Weird enough, I am getting a completely new set of warnings on other files 🙂

./alex

[Riyad Kalla]

Hrrm, that’s officially strange.

Sun’s JDK is what we test and develop with. What other kinds of warnings are you getting? Did you try and right click on the project, go to MyEclipse > Remove Validation Markers” then clean it just to make sure they aren’t stale?

[Alexandru Popescu]

Sure. I cleaned the project, removed all validation markers and build. This resulted in different warnings, including for example: “use !== null”. I finally got to switch back to JRockit, because with SUN JVM I am getting PermGen OutOfMemory exceptions, and so far I couldn’t identify what is wrong.

[Riyad Kalla]

Flip back to sun’s and just use this tip: http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-10087.html

the permSize issue is just a matter of different JVM defaults.

[Alexandru Popescu]

Unfortunately, things are not so simple. Here are a set of different options that more or less are finally resulting in the OOM:

 -Xms320m -Xmx640m -Xverify:none -XX:+UseParNewGC -XX:+UseConcMarkSweepGC

 -Xms320m -Xmx640m -Xverify:none -XX:PermSize=64m -XX:MaxPermSize=96m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC

-Xms256m -J-Xmx512m -XX:PermSize=64m -XX:MaxPermSize=96m -Xverify:none -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled

I have some few more on my list. Once again, unfortunately I haven’t been able till now to figure out what is the problem.

[Riyad Kalla]

If your 2nd or last one are still running out of perm space, I have to ask what do you have installed? You’d really need a full install of Eclipse + MyEclipse + lots more plugins to do that.

[Alexandru Popescu]

Yes they go from time to time in OOM. And indeed a have a full install of Eclipse + MyEclipse (is there any other way?). As for additional plugins, I don’t have too many: AJDT, SVN, TestNG.

./alex

.w( the_mindstorm )p.

[Riyad Kalla]

Weird you shouldn’t be getting out of perm space with that stuff… were you able to narrow down the errors? it sounded like they were pretty random depending on the VM used.

[Alexandru Popescu]

Here is a link to an open issue for Eclipse that tries to track this problem: https://bugs.eclipse.org/bugs/show_bug.cgi?id=129490
