Description

Options options = new Options();
options.addOption(Option.builder().longOpt("importToOpen").hasArg().argName("FILE").build());
options.addOption(Option.builder("i").longOpt("import").hasArg().argName("FILE").build());

Parsing "--import=FILE" is not possible since 1.3 as it throws a AmbiguousOptionException stating that it cannot decide whether import is import or importToOpen. In 1.2 this is not an issue.

The root lies in the new DefaultParser which does a startsWith check internally.
