Hi all,
I have barcode processing code in spring bean in tomcat.
I've added the following line to setenv.sh in tomcat bin directory.
export CATALINA_OPTS="$CATALINA_OPTS -Djava.awt.headless=true"
The web app runs well at the first time. After some time,let me say 1 or 2 days, exception ocurrs. Any clue would be appreciated.

Dig through the logs until you find the first error in the series. The few times I've seen errors like this one were an OOME followed by an incomplete attempt to recover from it. BufferedImage class has a native part, which once broken is not (to the best of my knowledge) fixable in Java.
OOME can happen not only when the memory is insufficient, but also when other types of native resources are insufficient: threads on file/stream descriptors are common abused such resources.
Keep in mind, that although ZXing Core *is* crashing it may very well *not* be the reason for the crash, but the victim of it.
