Dears,
I am trying to understand an error we start receiving in production
environment, after many days of normal behavior. As a result of this error
users receive an invalid PDF.
The error stack is below:
ExceptionConverter: com.itextpdf.text.DocumentException:
charter/resources/fonts/arialbd.ttf is not a true type file.

The file referenced "charter/resources/fonts/arialbd.ttf" exists and it is
the same for all environments, where the problem is not occuring, so I am
ruling out posibility of the file beeing corrupt.
I do not understand why all of a sudden it is reported as "not a true
type", while it was "good enough" for many weeks.
Also, I am assuming that if, for some reasons, java process could no longer
access the file, it would throw another IO exception, not "not a true type
file".
Can somebody please provide any help?
We plan to restart the servers during some maintenance period. Hopefully
the error will go away, but I am afraid the error may appear again.
Environment is linux redhat 5.7, weblogic 10.3.5, java
1.6_, itextpdf-5.3.5.jar
Thank you in advance,
Liviu
