The escape char is not showing up on the UI

[evelinec]

The test class has the following line of code that uses escape char:

1 <= Integer.parseInt(metric.split("\\s+")[metric.split("\\s+").length - 1]));

It shows up on the ol.io UI as:

1 <= Integer.parseInt(metric.split("\s+")[metric.split("\s+").length - 1]));

On Linux and Mac, the later causes a code compilation error:

/root/guides/PRs/guide-microprofile-metrics/start/src/test/java/it/io/openliberty/guides/metrics/MetricsIT.java:73: error: illegal escape character
            1 <= Integer.parseInt(metric.split("\s+")[metric.split("\s+").length - 1]));

@steven1046 @gkwan-ibm @NimG98 FYI

The above code is appearing correctly on the lgdev site as (\\s+).

But is showing up incorrectly as (\s+) on the QA site
https://qa-guides.mybluemix.net/guides/microprofile-metrics.html#testing-the-metrics

That line of code is new btw (added for dev mode) in branch mpMetrics2x (merged into QA)

I'm still looking into why this could be different on the QA environment. By the time the MetricsIT.java code gets loaded into html in the browser it already has one of the backslashes missing so it's not javascript that is doing this. And both environments have the same version of asciidoctor. I'm still lost as to why it is different but I'll keep looking.

temporary updated the guide by
Integer.parseInt(metric.split(" ")[metric.split(" ").length - 1]));
when this issue can be fixed by UI, the guide should be restored to
Integer.parseInt(metric.split("\\s+")[metric.split("\\s+").length - 1]));

pending a fix for OpenLiberty/openliberty.io#1975

Looks like the issue is in the minifier (https://github.com/octopress/minify-html) but unfortunately it doesn't seem like it's being actively maintained anymore (though we can certainly try and open an issue).
We're also looking at switching to a different minifier (#742) which may resolve this issue.

In the meantime, I suggest changing the example/test code to avoid this scenario.
