Myrna van Lunteren commented on DERBY-6350:
-------------------------------------------

I've not had a chance to further investigate either, except to say that there 
are 3 fixtures/methods that suffer from this behavior:
testStyleRollingFile()
testDefaultRollingDefaultConfig()
testDefaultRollingUserConfig()
(so the other failures were cascading from this).

I prevented these fixtures 3 from running (by renaming the methods to start 
with 'xtest' instead of 'test'), and ErrorStreamTest passed, and the 
engine._Suite suite passed also.

Windows is pickier about deleting files that have been accessed, we've seen 
that before, so this could just be a test cleanup issue...

> By default, derby.log grows without bounds if the derby.infolog.append 
> property is set to "true".   Setting this to "true" helps in a hands off 
> production environment to ensure that if Derby restarts, the derby.log which 
> might contain important information is not lost.  On the other hand, when set 
> the "true" the derby.log grows without bounds.  This is problematic in a long 
> running system.  
> What is really needed is the ability to have a rolling derby.log file support 
> where the maximum file size and maximum number of files can be specified.  
> Derby has the ability to configure the location of the log file (ie. 
> derby.stream.error.file) and also two methods of redirecting the error stream 
> (.ie derby.stream.error.method and derby.stream.error.field).  There is no 
> standard implementation that supports a rolling derby.log however.
> This facility should be part of the core Derby system so that it works in 
> both embedded and network server models.
