How safe is apache Commons-javaflow while using jasperreports

Question

I am using jasperreport and trying to pass an alternate report runner.

• net.sf.jasperreports.engine.fill.JRThreadSubreportRunner: The initial thread-based implementation

• net.sf.jasperreports.engine.fill.JRContinuationSubreportRunner: A Javaflow-based implementation

I am using the second one (for the reason, it runs on tomcat server, and creating threads wouldn't be good while writing subreports). The second one depends on commons-javaflow which is a sandbox version.

Not sure if I should use it, Could somebody suggest a better way. Thanks

Answer 1

While javaflow is a sandbox component, it is fairly mature, and many people use it in production. If have worked out all of the class-loader/bytecode transformer steps you need to take, it should be safe to use.

I would write several automated tests (just to be sure), and then use it.
