Memory Leak using Thumbnails.of(file).size(getWidth(),getHeight()).asBufferedImage(); about thumbnailator

[GoogleCodeExporter]

For what it's worth, the leak seems to be in the code that reads the file in.  
The following code does not exhibit the same problem:

                BufferedImage theImage=ImageIO.read(theFile);
                currentThumbnail=Thumbnails.of(theImage).size(200, 200).asBufferedImage();

But of course if you do it the way I just commented (read it in yourself) you 
lose the EXIF rotation which is why I started in the first place.

Doh.

I think I fixed it. Won't pretend to know exactly why. I knew something was not 
being disposed of properly, so I tried adding:
reader.dispose();

directly after:
iis.close();

Around line 155 of FileImageSource.java

Heap growth is now under control.

I feel like my morning was now spent productively. Hope to see this (or 
similar) patch soon :)

Hi,

Thank you for taking the time and effort to report this issue.

There appears to be numerous cases of Thumbnailator encountering 
`OutOfMemoryError`s when using Java 7 Update 21.

I just want to get a verification of which version of Java was being used when 
you encountered this problem. (I'm going to guess it's Java 7 Update 21, also 
known as Java 1.7.0_21.) 

Thank you!

No problem. So, I actually thought NetBeans bundled it's own JDK, but I may 
have been mistaken.  When I run the program and dump the appropriate system 
properties or just throw -version into the VM options, the answer is the same 
as from my OS X terminal window:
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06-451-11M4406)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01-451, mixed mode)

Thank you for the prompt reply.

It's interesting to note that the problem occurred on Java 6 Update 45.

However, that is the most recent version of Java 6 (and apparently the last 
update for 6), and the `OutOfMemoryError`s on Java 7 was also the most recent 
release, so it seems like something in the most recent release of Java is 
causing the memory leak to be more apparent.

Issue 42 seems to be the same issue, so I will be merging this issue into that 
one.

Once again, I really appreciate all the information and the prompt reply! :)

P.S. I'll try to credit the people who have reported and contributed to this 
issue in the "Changes", so if you'd like to be acknowledged, please leave your 
name or nickname you'd like to acknowledged by in this issue.
