ConcurrentModificationException when using replaceAll() on PersistentMap.builder() #68
Description
Calling replaceAll() on the mutable builder of a PersistentMap throws a ConcurrentModificationException.
Reproduction
To reproduce:
val pmap = persistentMapOf("a" to 1, "b" to 2)
val mmap = pmap.builder()
mmap.replaceAll { _, u -> u + 1 } // throws ConcurrentModificationException
mmap.build()
What I expected
A persistent map with the mapping "a" to 2, "b" to 3.
What I got
An exception:
java.util.ConcurrentModificationException
