How to pass -Djava.awt.headless=true to Report.__init__

[massimiliano-della-rovere]

in my code I have the following sequence:

prj = PyReportJasper()
prj.config(...)
prj.process_report()

and I get the following error:
NameError: Error fill report: Erro fill internal: java.lang.NoClassDefFoundError: Could not initialize class net.sf.jasperreports.engine.util.JRStyledTextParser
On the reportjasperforum, one user suggested to call java with the following cli option:
-Djava.awt.headless=true

I temporarily modified Report.__init__ inserting the headless option among the jpype.startJVM(...) parameters, and it worked.

How can I pass the headless option using the Config object?

I tried something like this:

prj = PyReportJasper()
prj.config(...)
prj.config.jvm_classpath = "-Djava.awt.headless=true"
prj.process_report()

but it did not work, and returned me another error:
NameError: Error fill report: Unable to import 'java.util' without JVM
