Extra empty line added before comments with // in method body

Is this behavior expected?

Before (from JHipster WebConfigurer.java)

    private void setMimeMappings(WebServerFactory server) {
        if (server instanceof ConfigurableServletWebServerFactory) {
            MimeMappings mappings = new MimeMappings(MimeMappings.DEFAULT);
            // IE issue, see https://github.com/jhipster/generator-jhipster/pull/711
            mappings.add("html", MediaType.TEXT_HTML_VALUE + ";charset=" + StandardCharsets.UTF_8.name().toLowerCase());
            // CloudFoundry issue, see https://github.com/cloudfoundry/gorouter/issues/64
            mappings.add("json", MediaType.TEXT_HTML_VALUE + ";charset=" + StandardCharsets.UTF_8.name().toLowerCase());
            ConfigurableServletWebServerFactory servletWebServer = (ConfigurableServletWebServerFactory) server;
            servletWebServer.setMimeMappings(mappings);
        }
    }

Actual:

    private void setMimeMappings(WebServerFactory server) {
        if (server instanceof ConfigurableServletWebServerFactory) {
            MimeMappings mappings = new MimeMappings(MimeMappings.DEFAULT);

            // IE issue, see https://github.com/jhipster/generator-jhipster/pull/711
            mappings.add("html", MediaType.TEXT_HTML_VALUE + ";charset=" + StandardCharsets.UTF_8.name().toLowerCase());

            // CloudFoundry issue, see https://github.com/cloudfoundry/gorouter/issues/64
            mappings.add("json", MediaType.TEXT_HTML_VALUE + ";charset=" + StandardCharsets.UTF_8.name().toLowerCase());
            ConfigurableServletWebServerFactory servletWebServer = (ConfigurableServletWebServerFactory) server;
            servletWebServer.setMimeMappings(mappings);
        }
    }

A side effect is that a new line is added before needles in code generated by JHipster

// jhipster-needle-entity-add-getters-setters - JHipster will add getters and setters here, do not remove

It is not done on purpose, but it is difficult to resolve this issue right now. As we might have to refactor the way we handle comments to fix #262, it might help to resolve this as well
