Your status says: Java version: 10+46, Oracle Corporation, Java HotSpot(TM) 64-Bit Server VM

That's Java 10 and not 10.0.1 → ​http://www.muchsoft.com/java/macosxjavaversions.html

Maybe you have more than 1 version installed and JOSM does not access the newest one?

Maybe yes, it would not be the first time, already happened in the past, basically Java isn't very smoothly integrated on Macs since Apple dropped support some years ago.

I've found another version at: /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java
although it is in "Internet Plugins", it is a command line java reporting this version: Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)

/usr/bin/java is linked to /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
(where Current is linked to A).

Maybe this is helpful to other mac users.

sudo rm /usr/bin/java
Password:
rm: /usr/bin/java: Operation not permitted

I'll have to put a link where it links to.

The version in /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java isn't shown:

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    10, x86_64:	"Java SE 10"	/Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home

So you should make sure at least the first entry listed above is up-to-date.
