Unable to run hosted mode due to byte code incompatibility with the JDK of WAS 6.1

[GoogleCodeExporter]

I use GWT with Gin integration under a Websphere Application Server 6.1 
environnement.

When I try to launch the hosted mode (GWT 2.2) I got this error at start time : 

WARNING: Use on a JRE prior to version 1.6 is deprecated
Loading modules
   com.jcdecaux.dynamo.presentation.Dynamo
      Loading inherited module 'com.google.gwt.inject.Inject'
         [ERROR] Unexpected error while processing XML
java.lang.UnsupportedClassVersionError: 
(com/google/gwt/inject/rebind/GinjectorGenerator) bad major version at offset=6

I think gin-1.5-post-gwt-2.2.jar has been compiled using a JDK 6, so my JDK 
(WAS 6.1) is not compatible with that compiled code.

Can you consider a recompilation of google-gin to keep compatibility with older 
 than 1.6 ?

I've attached the full stack trace in StackTrace.txt

I'll see what I can do. :)

Can you try out the attached jar and tell me whether it works? I compiled it 
for target "1.5" so presumably it should be compatible. If it works I'll update 
the release.

Hi, thanks for your quick answer but it seems there is no difference between 
this jar and the orginal (packaged) jar.

Further, I've checked the class file (GinjectorGenerator.class) using an 
hexadecimal editor and I get the same major version :
   CA FE BA BE 00 00 00 32

00 00 00 32 means JDK 1.6

Ah, I must have forgotten to clean my output directory or something last 
time... here is yet another jar, this one shows "ca fe ba be 00 00 00 31", 
which should be JDK 1.5. Let me know if this is better!

Since no one complained I have update the download file with the 1.5 compatible 
version.
