jdk 17中javax开头的包名都变成了Jakarta，导致包不兼容无法使用

I try to run an experiment with variables configured in "configuration"
"configuration":{ "waitTime": 3 }
There it´s defined as Number
Then I want to use this var in pauses

"pauses":{ "after": "${waitTime}"}

This results into an error that pauses needs a Number
Can it be fixed that variables can be uses also in "pauses" ?

Although it's not a high priority, we could get a more fancy and modern wheel.
