Pierre: I maintain the cheatsheet, and I put .indexOf and .lastIndexOf on there since they are probably the most common thing I saw asked about that is in the Java API but not the Clojure API, for strings. There are also links to whole Java classes and their entire API, e.g. for file I/O, for which there is no Clojure equivalent, since file I/O is a common need. Clojure is meant to be a hosted language, not hiding its host platform, but making it easily callable.
If there are entire Java classes that meet very common needs that aren't mentioned on the cheatsheet, I would consider adding links to their documentation pages. I don't want to fill up the cheatsheet with many individual Java methods, though. As for why there are not Clojure equivalents of particular Java API methods, I think the reasoning might be similar (it has likely been discussed publicly, but I don't have a link handy) -- don't create a large number of Clojure functions that do nothing more than what the equivalent Java APIs do.
