We could see that below errors are coming in adminui server.log during the startup. We are using external administration in our environment and LDAP is the external store.

Also sometimes we get these errors during Configure Administrative Authentication, we cannot set up the Super User ID as the Wizard can not find administrative user.


AdminUI r12.52 sp2 on windows 2012 r2, Java 1.8.0_31


This error is related to the Java JDK which is used by the adminui.

Below are the two different Oracle bugs that related to the error.




Please upgrade the java used by the adminui to Java 1.8.0_77 (here java version is 1.8.0_31).

Please follow below steps.

1) Take the backup of runtime folder from "PS_HOME\adminui". 

2) Run jdk-8u77-windows-i586.exe and have it install its items somewhere, then copy the contents of the new “…\jdk1.8.0_77” folder into "PS_HOME\adminui\runtime” 

OR You can choose the installation path to PS_HOME\adminui\runtime

3) Restart Admin UI
