Description
### Apache NetBeans version
Apache NetBeans 17
### What happened
When I add a remote java platform to my project and try to debug my project using this remote java platform, I get the error "Unable to create javax script engine for javascript".
I am using NetBeans' bundled Ant (1.10.8 as of writing this report)
### How to reproduce
1. Create a new Java Ant Project (File -> New Project -> Java with Ant -> Java Application)
2. Add a new Configuration in the project properties
3. Add a new Remote Platform in the project properties (localhost:22 as remote target on NonWindows platforms can be used, too)
4. Start debugging the project using the Remote Platform defined before
NetBeans will crash in the "jar:" step, remote-project-impl.xml:129: Unable to create javax script engine for javascript
Workaround: Force NetBeans to use OpenJDK 11 as default platform instead of OpenJDK 17
### Did this work correctly in an earlier version?
Apache NetBeans 12.6 or earlier
### Operating System
macOS 13.4
### JDK
17.0.7, OpenJDK, aarch64
### Apache NetBeans packaging
Apache NetBeans provided installer
### Anything else
NetBeans uses by default the standard JDK if it does not come with a bundled JDK. In my case this is OpenJDK 17. When I use an older version of OpenJDK (by editing /Applications/NetBeans/Apache NetBeans 17.app/Contents/Resources/NetBeans/netbeans/etc/netbeans.conf the line netbeans_jdkome to point to OpenJDK 11), the issue will be gone. Instead I get another issue, for which I will create a separate bug report.
The rest of the IDE seems to run well using JDK 17 so I think it is generally compatible with JDK 17, right?
I also think that the Ant version that comes bundles with NetBeans 17 (Ant 1.10.8) is not compatible with OpenJDK 17 (Since Nashorn has been dropped with JDK 15; the most recent version of Ant does not have this problem anymore)

Research direction
Start at remote-project-impl.xml:129 and compare the bundled Ant 1.10.8 behavior with the JDK 17 environment described in the report; the Nashorn removal is the reported compatibility clue. Reproduce the remote-platform debugging steps and consider the issue resolved when the project reaches the jar step without the JavaScript-engine error on JDK 17, without requiring JDK 11.
