Harald Kuhn commented on TRINIDAD-73:
-------------------------------------
Thanks.
This fix reduces the used file handles on first request from about 50 to 2.
That's great.
But I want to share two points I have noticed:
1) this fix seems to be useless if your webapp is deployed to Tomcat (Version
5.5.25) with option antiJARLocking="true".
This might be a Tomcat issue.
2) There are still multiple file handles for the generated css files

> When running a Trinidad application, trinidad-impl.jar is getting locked with
> open FileInputStream objects. When GC occurs, the FileInputStreams are
> getting cleared, but as new FileInputStreams are opened on each request, the
> file is eternally locked. Other files are likely getting locked too.
