There might be some specific security concerns related to the version of the Java JRE that is included in EEM, and you may wish to update to a newer JRE version. Included are the steps to update the JRE version.
EEM 12.5 or 12.6
Testing was performed with the following version of Java:
"1.8.0_161" (JRE 8 update 161), on the EEM server.
1. Shut down EEM
2. Install the Java JRE, and note the install path.
In this example it is installed to: C:\ProgramData\Oracle\Java\javapath
3. Update your PATH variable. The steps to do this will vary with the OS. See the reference below:
4. Define a system variable "JAVA_HOME" and specify the install path, in my example: "C:\ProgramData\Oracle\Java\javapath"
5. Restart EEM
