[news.eclipse.tools] JUnit problem following renaming a method

["Roger Nye" <Roger.Nye@xxxxxxxxxx>]

Hi,
I ran a JUnit test case on a single static method (called parseNumber)
successfully.
Then I renamed the method to parseInteger (with Refactor | Rename). The test
case updated appropriately.

But now the test case fails because it is still looking for parseNumber,
even if I delete all test case methods!

To be precise, it says:
    java.lang.NoSuchMethodError:
util.StringOps.parseNumber(Ljava/lang/String;I)I
    at util.TestStringOps.testParseNumber(TestStringOps.java:165)

I can find no reference to parseNumber in any of the relevant source files.
If I refactor the original method name back to parseNumber it works again.

I have tried rebuilding, restarting Eclipse, but still it wants parseNumber.

I am using Eclipse Version 2.1.0 Build 200303272130, under Windows 2000.
JVM is Sun 1.4.1_02 SE

Any ideas?

Many thanks
Roger
