NullPointerException getFontInfo

[doom160]

Hi,

I have been getting below exception in Prod environment which we could not replicate on our own environment and it has already occurred twiced this week. It seems like due to the nullpointer exception, the report can no longer generate. Other reports are able to generate. This report has quite a few SQL queries plus custom barcode fonts. I suspect it is due to the barcode font that causes this exception. This has not happened in the past. Please advice how should I resolve the issue.

This could be caused by the JVM. Does your local environment have exact same JVM as production? If not, I'd suggest to upgrade the production JVM to latest version.

This has not occur in the past. Yes both should be the same JVM, the only difference is production is installed on solaris whereas our local environment is on rhel. We will take your advice and try it out.

Thanks!
