15132	All islands [landuse=*] inside [natural=water] mapped as multipolygon are considered as ERROR by JOSM validation: 'Coastline inside natural=water'	AnkEric	team	"==== What steps will reproduce the problem?

JOSM Validation on:
multipolygon (""water""): 2-members
outer way = [natural=water]
inner way = [landuse=*] (which is an ""island"")

JOSM validation:
Error: ""Coastline inside natural=water""

Error is new to JOSM v.12542.

==== What is the expected result?

This is no Error.
IMO: multipolygon is correct.
Or:  ALL islands have been mapped incorrectly (meaning thousands).
