ADDITIONAL OS VERSION INFORMATION :
Darwin slytherin 11.4.2 Darwin Kernel Version 11.4.2: Thu Aug 23 16:25:48 PDT 2012; root:xnu-1699.32.7~1/RELEASE_X86_64 x86_64

(Mac OSX 10.7.5)


EXTRA RELEVANT SYSTEM CONFIGURATION :
Mac Pro 2.66 GHz Quad-Core Intel Xeon with 3 GB 1066 Mhz DDR3 memory. (I don't know if this is relevant.)

A DESCRIPTION OF THE PROBLEM :
Rendering an image with RenderingHints.KEY_INTERPOLATION set to
VALUE_INTERPOLATION_BICUBIC or VALUE_INTERPOLATION_BILINEAR causes
rendering to run very slowly, and renders twice when using
VALUE_INTERPOLATION_BICUBIC.


REGRESSION.  Last worked in version 6u45

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
  To maximize the effect, run this on the largest screen you can feasibly
use. Run the enclosed test case, which displays a test image in a
window. The repaint button lets you repaint the test image, and the
three radio buttons let you choose which type of interpolation to use
when repainting. Hit the repaint button to repaint using the default
nearest-neighbor algorithm. Then choose the Bi-linear interpolation
and hit repaint again. Observe the repainting speed. (The quality of
the black circle improves when you switch to Bi-linear painting, which
is how you can tell the painting is complete.) Then try this again
after choosing BiCubic interpolation.
Do all of this under JRE 1.6 and 1.7, and compare the results


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
For all three interpolation modes, painting of the image should be fast, and should not flicker.

ACTUAL -
I ran this on an Apple Cinema display, with the resolution set to 1920 x 1200.

Under JRE 1.6, I get the expected result. All three modes paint nearly
instantaneously. Under JRE 1.7, both Bi-linear and Bi-cubic paint
slowly. Bi-linear takes about 3 seconds, and Bi-cubic paints the image
twice, and takes about 5 seconds for both paints.


REPRODUCIBILITY :
This bug can be reproduced always.
