I'm able to reproduce this and have some idea of how we could go about fixing it. Can you confirm that just typing anything (even a space) in the file, restores the expected "Import List (java.util)" ?

This looks like a case of the AST model being stale resulting in some incorrect quick-fix suggestions. Modifying the contents of the file in any ways retriggers some operations that restore things.

Yes, if typing something before select code actions, all work fine.

Not exactly the same as eclipse-jdtls/eclipse.jdt.ls#1918 , but similar. Basically the cached AST model was out of date.
