I got annoyed by some of the daft names in Java, so I went through and found some of the worst offending method names. The longest method names I could find are "supportsDataDefinitionAndDataManipulationTransactions" (for Java Development Kit) and "setApplyWebRequestInterceptorsToRenderPhaseOnly (for Spring).
(see http://www.fatvat.co.uk/2011/05/method-names-in-java-develop...) for more details.
