3.0rc1
(javac does that)

in 1.5 enum is a keyword - we should have an options warning on all lower 
levels saying that this is the case. (just like with 'assert')

that was actually planned for all new 1.5 keywords, in 1.5 branch.

what are the other keywords?
i thought it was just enum.

Fixed and test added
  Compliance_1_3#test84()
  Compliance_1_4#test84()
  Compliance_1_5#test84()

The new compiler option is

* COMPILER / Reporting Usage of 'enum' Identifier
*    When enabled, the compiler will issue an error or a warning 
whenever 'enum' is 
*    used as an identifier (reserved keyword in 1.5)
*     - option 
id:         "org.eclipse.jdt.core.compiler.problem.enumIdentifier"
*     - possible values:   { "error", "warning", "ignore" }
*     - default:           "warning"

And added a new constant to JavaCore
  JavaCore#COMPILER_PB_ENUM_IDENTIFIER

Is it possible to turn this warning off?

Look at 'Preferences>Java>Compiler>JDK Compliance'.
Uncheck 'Use default compliance setting' and change the severity of 'Disallow
identifiers caller 'enum''.
