#29474

A problem reason and a workaround is explained in the post:
pdf-generation-troubleshooting-f4/getoutputstream-has-already-been-called-exception-t14.html

“getOutputStream() has already been called” error has different “fatality” on different JSP platforms, probably that explains why it works on Win and does not on Linux. But the best solution would be to update the JSP to suppress the error.
