Comment 5 Jaroslav Havlin 2014-01-17 11:02:50 UTC 
File name zipfsong.class (lower case 'z') was used instead of Zipfsong.class (upper case 'Z'). Which of the names is correct?

Did you work with the file in some other application or process in parallel?
Thank you for reporting.

Artificial Test Case

I've been able to reproduce the bug only in a test case which seems quite artificial.
If we change case of a file name while the original name is stored in FileObj instance, the assertNormalized will fail (see attached patch).

(However, detection of changed filename case can be costly. Currently we just use File.exists to check file validity during refresh. If we also had to compare canonical names, it would affect performance.)

I haven't managed to reproduce the bug manually in the IDE yet.

It would be very helpful to have real steps to reproduce. So, please, provide any addition information. Thank you.

Comment 12 Jaroslav Havlin 2014-01-31 16:15:13 UTC 
I've managed to reproduce the bug on Mac OS X.

Steps:

1. Open or create a Java project
2. Create file NewClass.java
3. Clean and build
4. Rename NewClass.java to Newclass.java (uppercase C to lowercase c)
5. Clean and build

Possible fix

A patch that seems to be working fine. But it needs to be tested carefully.
It makes refreshing slower (comparing with normalized names), and some tests fail.

Making assertNormalized less strict in some cases on Mac.
Thank you for reporting.
