Issues with Jdeveloper on Macbook

I will try to summarise issues I face during installation of Jdeveloper on my Macbook in his blog.

1- after installation I receive the message of “NullPointerException” .


I have installed the manually instead of running update from it from the normal update. The message gone.

2- running Weblogic-10 gives

starting weblogic with Java version:
Unrecognized option: -jrockit
Error: Could not create the Java Virtual Machine.

You receive this message because weblogic is still looking for jRocket which is not installed anymore on MacBook after upgrade to macOS Sierra.

Modify located in




before the line  (ln-160). # Set up JVM options base on value of JAVA_VENDOR. it should start.
