> The latest jdk9 releases (9+176) from the Oracle early access program omits the -ea suffix which was present in previous releases (e.g. 9-ea+170). This is causing the javadoc plugin to throw a StringIndexOutOfBoundsException under org.apache.commons.lang.SystemUtils.<clinit>(). Here is the relevant exception backtrace:

> After stripping the +nnn suffix SystemUtils assumes it has at least 3 characters to play with (looking at the line number 1133 for the substring call this appears to be version 2.4 that is being linked). It seems that this worked by fluke when the string contained the "-ea" suffix but it is now thoroughly borked. Perhaps an upgrade to 2.6 might work?
