[OpenJDK 2D-Dev] [9]RFR: JDK-7063986, , Wrong JNi method call in font scaler

[prasanta sadhukhan]

Hi All,

Please review a simple fix for jdk9
Bug: https://bugs.openjdk.java.net/browse/JDK-7063986
webrev: http://cr.openjdk.java.net/~psadhukhan/7063986/webrev/

It is found that the JNI invocation sun.font.Type1Font.readFile() from 
freeTypefontScaler.c is wrong.
readFile() type is void but JNI uses CallObjectMethod instead of 
CallVoidMethod.
Rectified JNI invocation in native to use correct CallVoidMethod.

Did not add any reg. testcase as I am not sure how to test this via a 
testcase.

Regards
Prasanta
