Will Upgrading Jasper Work?

[oilagan]

Hello All,

We've developed a system that uses jasper reports 1.2.1 java API that has been working fairly well for the past few years. There is a particular report in this system that produces a sort of employee resume in PDF format that is very much in use. Recently however, users have started reporting instances when running the report for certain employees produces a browser timeout. And consistently, after the third occurrence, the system becomes unresponsive altogether requiring a server restart. After attempting quite a number of diagnostic attempts, we have determined that it is not an application nor a server problem. However, we would like to avoid having to upgrade jasper reports because this involves a re-testing of all the other reports (there are hundreds of them) which did not exhibit the same problem and there is no guarantee yet that it will work. So we would like to know if this problem has been reported before and if so how was it solved. I have been trying to test a theory that it is caused by certain special characters that were read from the database but I have not been able to prove this so far.

The system uses java servlets with jdk 1.6, postgres 8.1 database in UTF-8, and itext 1.4
