Summary: PNG files locked until JVM exits
Product: Fop
Version: 1.0dev
Platform: PC
OS/Version: Windows Vista
Status: NEW
Severity: normal
Priority: P2
Component: images
AssignedTo: fop-dev@xmlgraphics.apache.org
ReportedBy: [EMAIL PROTECTED]
This might actually be a problem in xmlgraphics-commons, but I'm not sure. It
appears that if an FO file makes an external-graphic reference to a PNG file
and renders to either PDF or PostScript (those are the only 2 I tried), the PNG
file remains locked until the JVM exits. Note that if there are multiple
external-graphic elements only 1 or the last 2 are locked.
To summarize the application flow:
1. Write PNG files to directory and close them
2. Create FO file containing external-graphic reference to those PNG files
3. Create PDF file through FOP
4. Delete PNG files
The File.delete() call fails on some of the PNG files.
I tried this same test with JPG files and they all deleted just fine. I'm
guessing that somewhere an InputStream isn't getting closed.
