<AWT Dev> RFR JDK-8171836: Memory leak in java.desktop/unix/native/common/awt/fontpath.c

[Ambarish Rapte]

Hi Abhijit,

                There can be references added to newFontPath[] in previous iterations of loop at Line 298: newFontPath[nPaths++] = onePath;

 

                So these references should also be freed, something similar to code at line 308:

 

                for ( index = origNumPaths; index < totalDirCount; index++ ) {

                                free( newFontPath[index] );

}

 

As many references added to newFontPath should be freed accordingly.

 

Regards,

Ambarish

Abhijit, 
I think there's some misunderstanding here.
The pointer you are trying to free is NULL already:

     if ( newFontPath == NULL ) {
       free ( ( void *) appendDirList );
+      free((void*) newFontPath);

Thanks,
Vadim

To prevent memory leak issue, I have released the newFontPath in java.desktop/unix/native/common/awt/fontpath. 
Moving forward it for review.
