Critical tools that every Java Developer should have in his toolbelt?

Question

I was trying to compile a list of tools that a good Java Developer should be know of, and keep in his Developer Tool Belt

I can think of a few

Eclipse Development Environment - There are other IDEs, but you should know how Eclipse of eclipse.
JUnit - Java Unit Testing Framework. Of course there are others, but...
ANT
Maven
Soap UI - for testing SOAP endpoints
jrat - Java Profiler. I don't know of other good Java profilers
Java Decompiler - For when you just have to know what's in the jar file

Comment to my own post: The question is about tools, not libraries. Something that would be applicable no matter what functionality you are trying to implement. — Timur Fanshteyn, Apr 12 '10 at 21:16
@Timur: Then I think, Soap UI doesn't really fit in. Lots of Java developers/projects don't use SOAP. — Chris Lercher, Apr 12 '10 at 21:18
True - But I think it is important enough for a java developers to know of its existence and to use it when service testing is required. — Timur Fanshteyn, Apr 12 '10 at 21:25
@Oscar No matter what IDE you use for JAVA development - you shouldn't be surprised if your next project requires eclipse. — Timur Fanshteyn, Apr 12 '10 at 21:32
By using maven I found that my IDE now needs to work around my project instead of the other way around =) — Pyrolistical, Apr 12 '10 at 23:10

Continuous integration server: CruiseControl, Hudson, etc.
Dependency injection: Google Guice, Spring, PicoContainer
Slf4J: Simple Logging Facade for Java
Mockito: Mocking Library
Not Java specific but nonetheless essential: a good distributed source control (Git or Mercurial)

VisualVM - for low level memory profiling
Eclipse MAT - for high level memory profiling
JMeter - for performance testing
Mockito, EasyMock, PowerMock - for mocking
FindBugs, Checkstyle, PMD - for static code analysis

Hudson, near the top of the list.
visualVM - good enough for most profiling needs (and I've heard of a number of Java profilers, but never of jrat)
Cobertura or Emma for code coverage
