unable to retrieve handle

[zwindvincent]

Dear all,

I am using the the imagemagick 6.2.8 Q16 and the tomcat 5.5 to develop my program and face the following problem:

13:27:08,384 ERROR [EPassSuppDocBuilder] (AppScheduler_Worker-1) Image conversation failed, keep original!

Does anyone has any idea of what's wrong with it?

Nearly forget to mention , the most tricky point of this bug is that when the program is rerun again , this error DOES NOT COME OUT again. i.e. this is a random error during the running of the program
