As much of a fan as I am of Java, I have to agree. There are some real bombshells in the library that can either make your coding life or debugging a prod service miserable (sometimes both). Other additions are great, but have hurt readability a bit (i.e. Java lambdas).
Checked exceptions get a bad rep, but I've frequently found taking advantage of their hierarchical nature can be beneficial to at least making them less bad to catch. When I work with languages that have no exception support at all, I sometimes even miss them.
