Company completion overwriting existing text

Question

I am using company with lsp-java, but I think this is a company problem. I have some code like

  void quz(int bar, int longNamedVariable) {
    foo(bar, longNamedVariable);
  }

I packaged all the parameters into a container object, so now the function signature is quz(Data data). When I got to update the call to foo, I put the point before bar and type data.get. At this point, I get getBar() and getLongNamedVariable() as completion options. When I press RET to access getBar(), it overwrites the remaining text on the line, so I end up with

  void quz(Data data) {
    foo(data.getBar(),Variable);
  }

where part of the following argument is overwritten. I can't imagine that this is the intended behavior and it is certainly disruptive. Any ideas what is causing it and what I can do to get it to work correctly?

In case it is not clear, "work correctly" means that after completion, I have

  void quz(Data data) {
    foo(data.getBar(), longNamedVariable);
  }
