iReport won't launch

[geston88]

I have installed iReport Designer in version 5.5.1. When i'm launching this app appears small blue screen iReport with info about loading etc, and that's all, disappears and nothing happens, without errors.

Can anyone help me, or tell where should I search any logs or sth.

Thanks.

ok solved... I had installed only jre 8.5, after installing java 7.55 - works fine.

JasperReports doesn't support jre8 yet.
