(paraphrased)

Client: Would you please restore a file I accidentally deleted? I know you can only restore to yesterday's date, but we did a lot of work today and need it to be current.
Me: Doh!

I received an SMS message (text message for those Americans amongst you) this morning at 07:04 from my wireless service provider, proclaiming to have given me a free 1GB of data per month. All I had to do was to click the link to enable it.

Firstly I was suspicious at the time the message was sent. My carrier has never sent me an SMS message that early. Secondly, the number did not match anything I associate with them - but that is a bit tenuous as they sometimes use weird internal numbers. The URL in the message (partly blocked out) did seem reasonable but also not exactly what I thought it should be.

 java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long

In specific, all I want to do is use a JSTL variable as index to a variable someMap as follows:

Map<Integer, SomeObject> someMap = new HashMap<>();
...
<c:forEach begin="0" end="10" var="level">
    <c:out value="${someMap[level]}" />
</c:forEach>

This...

or seeing this the next day...
