Make game crash with crash report

Hello

I want to make game crash with a crash report when my reflection fail.

I know class CrashReport but I don't know how to use it.

I've done :

}catch(ReflectiveOperationException e) {
CrashReport crash = new CrashReport(e.getLocalizedMessage(), e);
FMLCommonHandler.instance().enhanceCrashReport(crash, crash.makeCategory(ForgeCreeperHeal.MODNAME));
}

But nothing happens.

I know there are a lot of possibilities that this question have already be posted but search engines always redirect me on support topic where people looking for help because their game have crashed.
