Change JDK for OpenDJ 3 from 7 to 8 keeps giving error

[sphsms]

Currently I have Java 7 being used but I would like to point Java 8 to be used for OpenDJ 3. My current system:

Linux 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Following is what I am trying:

[At this time opendj is already running]

1. Edit java.properties file in /opendj/config file with these values:

default.java-home=/usr/local/java/jdk1.8.0_91 [earlier it was /usr/local/java/jdk1.7._49/jre]
start-ds.java-args=-Xms4G -Xmx4G -server [earlier it was start-ds.java-args=-Xms128m -Xmx256m -server]

2. In /opendj/bin, run dsjavaproperties for changes to take effect.

The operation was successful. The server commands will use the java arguments
and java home specified in the properties file located in
/apps/opendj/config/java.properties

3. Stop OpenDJ [Server stops successfully]

4. Start OpenDJ

I get the following :

ERROR: The detected Java version could not be used with the set of Java
arguments -Xms4G -Xmx4G -server.
The detected Java binary is:
/usr/local/java/jdk1.8.0_91/bin/java
You must specify the path to a valid Java 7.0 or higher version.
The procedure to follow is:
1. Delete the file /apps/opendj/lib/set-java-home if it exists.
2. Set the environment variable OPENDJ_JAVA_HOME to the root of a valid
Java 7.0 installation.
If you want to have specific Java settings for each command line you must
follow the steps 3 and 4.
3. Edit the properties file specifying the Java binary and the Java arguments
for each command line. The Java properties file is located in:
/apps/opendj/config/java.properties.
4. Run the command-line /apps/opendj/bin/dsjavaproperties

No matter what I try it keeps giving a similar error. I tried doing just steps 1 and in the above suggestions by setting OPENDJ_JAVA_HOME to point to Java 8 and deleting set-java-home file but no change. What am I doing wrong? Any help will be appreciated.

Could it be that you have installed the 32 bit version of the JRE (i586) and not the 64 bit one (x64) ?

You were right. Wrong Java. After that just changing java.properties file and running dsjavaproperties worked as expected. Sorry to have bothered you and wasting your time. Thank you for your help.

You’re welcome. I believe the only time I had issues with -Xms and -Xms were for the same reason :)
