Records are called „methods“ in JShell

[Lingo Coder]

Hi,

Thanks for looking into this, Jorn.

I'm sure :)

I checked, rechecked and then, finally, rechecked that I rechecked. 

How I (re)checked:

1. I cleared the value of $PATH in the terminal where I run JShell
2. I then set the value of $PATH to be the file system location of the
   one and only installation of OpenJDK 15-ea (build 15-ea+31-1502)
3. I checked that the value of $PATH had only the one single entry
4. Does java -version report build 15-ea+31-1502? Confirmed!
5. I launched JShell
6. Created a record named „JShellChecker“; 
7. Observed JShell reports: „created *method* JShellChecker“
8. Edited the record to implement a JShell .exe location check
9. JShell reports: „replaced *method* JShellChecker“

Observe [1] to check that it is really happening as I describe.

TIA.

Hi,

I was not able to reproduce this with JDK 15 build 31 (the same version 
that you are using).

PS C:\Program Files\Java\jdk-15-b31\bin> ./jshell.exe --enable-preview
|  Welcome to JShell -- Version 15-ea
|  For an introduction type: /help intro

jshell> public record Point(int x, int y) {}
|  created record Point

jshell> /drop Point
|  dropped record Point

Are you sure that you are using the right jshell executable, and it's 
not picking up another one that's on the PATH as well?
