preview with jasperreport4.7 and jdk8

[whaojun]

we have a project using jasperreport4.7 and jdk6, and now we have to upgrade jdk6 to jdk8.

 

we noticed that jdk8 doen't support jasperreport4.7 , so we use the code below to avoid security check, and it worked.print is ok.

AccessController.doPrivileged(new PrivilegedAction()[/code]

but when using preview, it doen't work, the preview window can be opened but there is noting on it, and the whole window sized up. any suggustiong??
