The JPEG encoder crashes on Win32.

Attached is a sample testcase that works fine on any Solaris os,
but crashes on Win98, NT and 2K. The testcase was tested on B84
and B83.
The problem doesn't seem to be there for PNG encoder.

Steps to reproduce.

1. Create a resources directory and save the Render2DTest.properties file
   to this folder. Compile Render2DTest.java file.
2. Launch the applet 'appletviewer -Xnosecurity Render2DTest.html'
3. You would find a frame with 4 radio buttons and 3 buttons.
4. Select 'JPEG-Shape' radio button.
5. Click on BuffImage, Write and Next buttons rapidly in succession, the
application crashes in 3rd or 4th round. This is seen easily on Win2K.
6. On Win 98 and NT, follow the above 3 steps. Keep on clicking the next
button, till you see TYPE_BYTE_BINARY format.
7. Click on BuffImage and then Write button, JVM crashes.

The stack trace on Win98 is as below. On Win2K, each time it crashes
at different points.

Another testcase that verifies if the JPEG decoder used by Toolkit.getImage() can successfully read JPEG files created by using ImageIO with YCbCrA and RGBA colorspaces.
