### What changes were proposed in this pull request?
This PR reverts https://github.com/apache/spark/pull/27860 to downgrade Janino, as the new version has a bug.
### Why are the changes needed?
The symptom is about NaN comparison. For code below
```
if (double_value <= 0.0) {
...
} else {
...
}
```
If `double_value` is NaN, `NaN <= 0.0` is false and we should go to the else branch. However, current Spark goes to the if branch and causes correctness issues like SPARK-32640.
One way to fix it is:
```
boolean cond = double_value <= 0.0;
if (cond) {
...
} else {
...
}
```
I'm not familiar with Janino so I don't know what's going on there.
### Does this PR introduce _any_ user-facing change?
Yes, fix correctness bugs.
### How was this patch tested?
a new test
