A DESCRIPTION OF THE PROBLEM :
The documentation for JVMTI at
https://docs.oracle.com/en/java/javase/24/docs/specs/jvmti.html#GetLocalDouble
States:
"This function can be used to retrieve the value of a local variable whose type is long."

I believe this to be wrong, probably a copy paste error from the GetLocalLong.

I think the correct wording should be:
"This function can be used to retrieve the value of a local variable whose type is double."

The error is in the last word, where the current documentation says "long" instead of "double".
