GWT plugin 3.8.0 v201410302155 r43 with GWT 2.4.0 SDK : superDevMode argument auto injected in Google Run Target + warning missing gwt-codeserver.jar ? under GWT preferences

[GoogleCodeExporter]

Found in GWT Release 2.4.0:

Encountered on OS / Browser (Win7, IE9, FF10):

Detailed description (please be as specific as possible):
Update on GWT plugin changes my GWT preference and option in GWT Run target 
failing in GWT 2.4.0 SDK as -superDevMode arg not supported.

Shortest code snippet which demonstrates issue (please indicate where
actual result differs from expected result):

Workaround if you have one:
adding gwt-codeserver.jar to 2.4.0 sdk remove the warning but not sure as 
linked to superdevmode not available in 2.4.0

the latest version of the GWT Plugin under Eclipse remove the issue since 
3.8.0..r44 the noSuperDevMode option appears and the superDevMode is not 
automatically addded.

The solution (more a workaround) is to add the codeserver.jar temporary under 
the GWT 2.4.0 SDK folder to add it under the Eclipse > Window > Preferences > 
Google > Web Toolkit (Add...)

Once your GWT project have the GWT Container added to your classpath, you 
should be fine and you can remove the codeserver.jar . Still remain the warn & 
error under Eclipse > Window > Preferences > Google > Web Toolkit but it works 
fine.

Hope it will help.

Beside I was aware of too long classpath resolution on GWT SDK 2.7 but I cannot 
the find any references in the Release notes, any help is helpful. Our project 
get so many jars dependencies throught maven that the classpath that it is 
getting a real issue (BTW no support of Bundle ClassPath by GWT so far...one 
day maybe)

To stop the -superDevMode flag from getting auto injected I made the Eclipse 
Run Configuration file read-only.

Example path: 
<YOUR_WORKSPACE>\.metadata\.plugins\org.eclipse.debug.core\.launches\<YOUR_RUN_C
ONFIG_NAME>.launch

Then whenever you look at the Dev Mode Run Configuration in Eclipse it will 
still show the -superDevMode flag, but when you click the Close button it now 
asks you if you want to save and you can press No.

On a somewhat related note: if you decide to hand edit that .launch file in a 
text editor Eclipse won't notice your changes. Just restart Eclipse though, and 
it'll see your changes.

Thanks for this idea... little hack... I guess we have to move to 2.7 

Do you have any feedback on GWT classpath too long issue ?

this issue, but haven't yet rolled a release including the fix:
