On Integrated development environments

The main problems I find with the Eclipse IDE are:

• Eclipse does not remove whitespace at end-of-line. It seems the eclipse based JBuilder does this flawlessly.
• Eclipse does not have a good spaces vs tabs behavior. I think if eclipse it is not going to stick to 8 spaces indentation by default it should be using spaces everywhere by default instead of changing a well defined a tab is 8 spaces de facto standard.
• Eclipse is still using non standard character encodings on some platforms like MSWindows. Change the default encoding to UTF-8 in Eclipse. (If you read this bug thread you will see how old fashioned an IBM engineer can be)
  
• Eclipse does not recognize new JARs of Java EE applications in WEB-INF/lib until you restart eclipse.

The features I need from an IDE are:

• Code refactoring: I want to be able to rename a method or variable without renaming other different equally named variables.
• I need to know the callers of a function to know the consequences of changing its behavior.
• I need VCS integration to know the current changes and be able to quickly change branches to develop new features.
• I need automatic compilation and verification.
