I'm compiling 143 reports using JRAntCompileTask with Jasperreport 6.17. Under Java 8 it takes 40-45 seconds. Under Java 17 it take 110-155 seconds.

What is your operating system? Do you have the ECJ (Eclipse Compiler for Java) JAR in your classpath?

Thank you, Teodor

Feel free to reopen this in case you can provide more details about the problem. I'm attaching here a zip with dummy reports that you could drop into the /demo/samples/antcompile folder of your JRL project distribution and try compile them with different Java version to see if there is a difference. I did not notice a significant different on my side.

Thank you, Teodor reports.zip
