GT Subset - Java Runtime Environment error message at launch - This application requires a Java Runtime Environment 1.6.0

Products

• CA Test Data Manager (Data Finder / Grid Tools)

Issue/Introduction

We recently started to get this error message when we launch GT Subset so the tool is unavailable.

It was working fine before the holidays(back in november). I know that we removed Oracle Java Runtime tool from our servers since TDM Portal and FDM has their own JRE included and also because it was a recommendation from our Middleware team also.

Could this be related? If so, is there a way to tell GT Subset to use the JRE of TDM Portal or FDM instead?

Environment

Release : 4.9.1

Resolution

The root cause is "more than likely" a security "vulnerability" pointed to our installation of AdoptOpenJRE software.  

Software Requirements The following software is required for Test Data Manager installation. Java JRE: AdoptOpenJDK JRE 8

Our component, GTSUBSET.exe, REQUIRES the Java JRE: AdoptOpenJDK JRE 8.  With that not on your system, you will experience the failure that you are experiencing.  By creating/importing the keys and modifying the paths  supplied, this will resolve your issue.

You can try to adjust & test the following registry import:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft]

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]
"CurrentVersion"="1.8"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.8]
"JavaHome"="C:\\Program Files\\AdoptOpenJDK\\jre-8.0.212.04-hotspot\\"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\8.0.212.04]
"JavaHome"="C:\\Program Files\\AdoptOpenJDK\\jre-8.0.212.04-hotspot\\"

 

the Recommended method is Development found a root cure for the issue with Subset without having to change the registry keys.  GTDatamaker (which includes Subset during the install) has been changed so it is looking for the embedded JRE.
