[Jetty-support] ResourceCache bug?

[Simon D. <sim...@ma...>]

Hello,

I'm running Jetty 6.0.1 on Windows XP with Java 1.5.0_06 using both Firefox=
 2.0 and IE 6. I'm running Jetty embedded in an application which creates j=
pg images with unique id's which it then deletes 5 seconds later. My webdef=
ault.xml has useFileMappedBuffer set to false as described in - http://docs=
.codehaus.org/display/JETTY/Files+locked+on+Windows

I find that after running for a while I get the following which requires th=
e application and Jetty to be restarted :

2006-11-23 13:16:26.071::WARN:  /SensorNet/image4937593.jpg

This happens everytime a new image file is created even though the old one =
is deleted as it should be. If I run the application with useFileMappedBuff=
er set to true, the image files obviously aren't deleted but jetty works fi=
ne.
A possible bug?

Thanks
