OpenJDK and IcedTea security settings

[Xpdin]

I am a beginner Linux user. From my knowledge the system uses OpenJDK and IcedTea only when I connect to a SAP IDES server through SAP GUI JAVA adding a string in it to connect to that server. I use SAP for my studies.
What is SAP IDES

I have the next 3 questions please, I will number them to be easier for you to answer:

1. How can I check if only the SAP GUI JAVA from all Lubuntu and other installed applications need and use the OpenJDK and IcedTea.

2. If only SAP GUI JAVA from my entire system needs OpenJDK and IcedTea, are there any security settings using these two commands

    itweb-settings

and

    IcedTea-Web

or using other commands to set the OpenJDK or IcedTea to accept connections to them only from SAP GUI JAVA, and only from the IDES server please?

3. Which other security settings do you recommend to set to OpenJDK and IcedTea, like filtering the IDES and SAP connection?




Thank you very much and all the best to you all !
