CA DevTest is certified only in Java 8 & there has been some resolution issues for Windows 10\Java 8 combination. Issue occurs in specific steps such as WS step.
Resolution issue seems to be tied with Java 8 & may not occur in Java 9 as per CA support.
Minor workarounds may not work in a long term as many teams use the same feature
CA DevTest Product is not certified in Java 9 yet. In order to roll-out the fix across the teams, the product has to be certified in Java 9.
Would be appreciated if it can be taken up on priority
Note - Can provide the case # if needed
