Some libs like axios js use the square brackets notation when sending a multi-value param request: /stats?store[]=A&store[]=B&item[]=C&item[]=D

To handle all cases (with or without square brackets) you can add another param like this:

public String methodImCalling(
  @QueryParam(value = "store") final List store, 
  @QueryParam(value = "store[]") final List storeWithBrackets, 
  @QueryParam(value = "item") final List item,
  @QueryParam(value = "item[]") final List itemWithBrackets) {
...
}

Inspecting each of the arguments checking for null.
