This issue could be caused by having an additional installation of Java on the SDM server, outside of the one used by SDM.
Firstly confirm if there is, in fact, another instance of Java on the server. One method of doing this is to open a command prompt on the server and run the command:
By default, even with Service Desk installed, this command should fail. If it does return a Java version, then validate what the version is.
Secondly, confirm if Java is actually needed on the server. As mentioned SDM does not need an additional install of Java, as it will use the one referenced in the NX.env file's value:
If Java is not actually needed for anything else, you may want remove it completely. If there is some specific reason for having an installation of Java, you should consider using the same version of Java that is used for SDM to avoid potential conflicts.
