While Java 8 has Double.isFinite, Java 7 unfortunately doesn't. With CS50 IDE still on Ubuntu 14.04 (and CS50 CLI similarly fixed at Ubutu 14.04 until CS50 IDE changes), building edu.harvard.CS50 yields:

$ javac -d build src/edu/harvard/CS50.java 
src/edu/harvard/CS50.java:122: error: cannot find symbol
                    if (Double.isFinite(d) && d < Double.MAX_VALUE)
                              ^
