Hello everyone,
we did a migration from JDev/ADF 11.1.1.7.0 to 12.2.1.4.0 (Build JDEVADF_PT.12.2.1.4.0_GENERIC_190911.2248.S).
The application seems to be working fine, except for the special characters coming from our resource bundles.
We have French as a second language in our application. The labels for buttons and links and fields are stored in resource bundles. These files are UTF-8 encoded. Opening the files in JDev shows the correct characters.
Running the application results in words like :

Being Récupérations and Sécurité.
We believe that somehow the JRE is not running in UTF-8 mode.
The information coming from the database is correct. Data from the db is showing the special characters correctly. Only the ones that are coming from the resource bundles are giving these strange characters.
This problem did not exist in the 11g version.
The problem present itself in the embedded WLS and a standalone WLS instance.
Anyone any idea to solve this?
Thx
