On the first release of jdeveloper 11, I had made a post that jdeveloper is not ready.
After 4 patches I feel now that jdeveloper 18.104.22.168 and ADF is ready to use for development of large scale enterprise applications.
The basic bugs have been minimized and the IDE have been stabilized.
We migrated the 46000 files (1GB) adf application to 22.214.171.124 without any serious issue apart from fixing the jazn-data.xml according to note 1288757.1 - Policy Migration of the "jazn-data.xml" File Fails Silently in JDeveloper 126.96.36.199.0.
We are also working now with java 64 bit on windows and set the following configuration :
Set in jdev.conf file (in $Middleware_Home$\jdeveloper\jdev\bin) depending on java installation path:
Set in ide.conf file (in $Middleware_Home$\jdeveloper\ide\bin) depending on the available memory:
The low memory messages have been minimized.
I would like to congratulate the jdeveloper team for their work and wish the best for the future.
