Why no data shown in the report after upgrade to 4.13 from 4.4.2 (RedHat JDK 11) even without exeption?

[davidwwd2011]

Previous running report with Birt 4.4.2 is recently upgraded to 4.14.0 (also tried 4.13.0). Though View report in Eclipse shows the report with data correctly. But when running the applicaiton, empty report is displayed but no data is get into the report even though with same parameters. No exceptions reported except some warnings:

Are you sure that you are using BIRT 4.14.0 and removed the BIRT 4.4.2 libs? Is your runtime environment clean?
For example, BIRT 4.14 does not use iText anymore. It has been replaced with OpenPDF.

Thannk you, @hvbtup, for the reply. I have replace all the itext 2.1.7 with the OpenPDF (com.github.librepdf) 1.3.33. Now no warning anymore. However, the report is still empty when running applicaiton (though template View PDF works). There are some font related INFO messages (using 4.13):

Since no official latest Eclipse Birt Maven runtime is available, I use @siepkes' (https://gist.github.com/siepkes/00f0c410933271b4f4e0d5eab18d7469) for install the related jars.

Do I miss anything? Kind advices would be highly appreciated.

I'm sorry I can't help you. I never experienced such an issue.
It is probably a result of your custom environment or your application just doesn't find anything.

Most existing reports should work with BIRT 4.14 without a need to change anything.
A known exception to this rule is Javascript code in your BIRT report that tries to use custom Java classes.
Due to the Java module system they may result in illegal reflective access operations. These result in exceptions with Java 17 (no longer just warnings).

[hvbtup]

And BIRT 4.14 requires Java 17...

I am now using 4.13.
