How to specifically suppress “Comparing identical expressions” in Eclipse-Helios JDT

Question

I tried annotating the enclosing method with

    @SuppressWarnings("compareIdentical")

but this does not work (worse yet, the annotation results in its own Unsupported @SuppressWarnings("compareIdentical") warning!)

I know that I can always use

    @SuppressWarnings("all")

but that'd be more warning-suppression than I want.

FWIW, I got the "compareIdentical" string from the "Warning Options" table in http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.jdt.doc.isv/guide/jdt_api_compile.htm (a hail-mary pass, to be sure).

Thanks!

The list of tokens that can be used inside an SuppressWarning annotation is:

• all to suppress all warnings
• boxing to suppress warnings relative to boxing/unboxing operations
• cast to suppress warnings relative to cast operations
• dep-ann to suppress warnings relative to deprecated annotation
• deprecation to suppress warnings relative to deprecation
• fallthrough to suppress warnings relative to missing breaks in switch statements
• finally to suppress warnings relative to finally block that don't return
• hiding to suppress warnings relative to locals that hide variable
• incomplete-switch to suppress warnings relative to missing entries in a switch statement (enum case)
• nls to suppress warnings relative to non-nls string literals
• null to suppress warnings relative to null analysis
• raw to suppress warnings relative to usage of raw types
• restriction to suppress warnings relative to usage of discouraged or forbidden references
• serial to suppress warnings relative to missing serialVersionUID field for a serializable class
• static-access to suppress warnings relative to incorrect static access
• super to suppress warnings relative to overriding a method without super invocations
• synthetic-access to suppress warnings relative to unoptimized access from inner classes
• unchecked to suppress warnings relative to unchecked operations
• unqualified-field-access to suppress warnings relative to field access unqualified
• unused to suppress warnings relative to unused code and dead code

So, there is nothing which might help you.
