Virtualizer cleaning error

2006-03-01 10:27

Hi, I'm using Virtualizer to generate my reports. I notice that sometimes it appears the following error:

1/Mar/2006 18:15:28 net.sf.jasperreports.engine.fill.JRFileVirtualizer cleanup

SEVERE: Error cleaning up virtualizer.

java.lang.NullPointerException

at net.sf.jasperreports.engine.fill.JRFileVirtualizer.makeFilename(JRFileVirtualizer.java:221)

at net.sf.jasperreports.engine.fill.JRFileVirtualizer.fileDispose(JRFileVirtualizer.java:283)

at net.sf.jasperreports.engine.fill.JRFileVirtualizer.cleanup(JRFileVirtualizer.java:310)

at net.sf.jasperreports.engine.fill.JRFileVirtualizer.finalize(JRFileVirtualizer.java:215)

at java.lang.ref.Finalizer.invokeFinalizeMethod(Native Method)

at java.lang.ref.Finalizer.runFinalizer(Finalizer.java:83)

at java.lang.ref.Finalizer.access$100(Finalizer.java:14)

at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:160)

 

It seems that this message is sent by an automatic process. Can it be? How can I control (activate or deactivate) it?

 

I'm making manually the cleaning of the temporary files.

 

Thanks,

Ana

Hi

 

This has been reported before:

https://sourceforge.net/forum/forum.php?thread_id=1443528&forum_id=113530

 

The cleanup performed on JRFileVirtualizer finalization fails because of a bug in prior executed code. The CVS version includes a fix for the issue.

 

You can patch your sources with the fix or simply ignore the exception for now as it's only logged and doesn't have any other effect.

 

Regards,

Lucian
