Hi,
Please:
1. Review the following KM Which version of GWT is supported in LoadRunner 11.50? to check if GWT version is supported or not.
2. Additionally what is the Java version used for compiling the application: is it 1.6 or 1.7. Is it 34 or 64 bit one?
3. It will be useful to check if the war file contains some corrupted jar files because it could cause issues.
4. You can also review the following link in the forum

Kind regards,
