Description
Code Analysis to understand usages of SharedBuffer and SimpleSharedBufferInputStream in JavaFX API
Comments
Good. This means that we can consider this a test bug and not a product bug.

There is only one method call which takes SimpleSharedBufferInputStream as input parameter, as mentioned below:
private WCFontCustomPlatformData fwkCreateFontCustomPlatformData(
SharedBuffer sharedBuffer)
{
try {
return createFontCustomPlatformData(
new SimpleSharedBufferInputStream(sharedBuffer));
fwkCreateFontCustomPlatformData is called from native webkit and also, it is a private method. Hence, it is not an exposed api.
Hence, as per the current code usage, we can conclude that the usage of SharedBuffer and SimpleSharedBufferInputStream in unit tests needs to be rewritten.
Also, we can say that SharedBuffer and SimpleSharedBufferInputStream are not accessible via public apis in JavaFx

From the usage in Java apis, it is observed that SharedBuffer is only used in SimpleSharedBufferInputStream, which in turn is used in createFontCustomPlatformData. Further analysis in progress.
