test java/awt/FontClass/TestFontCache/TestFontCache.java failed on 1.3.1_23-b01 but passed on previous one 1.3.1_22-b03

test checks next one:
 * @summary invoke deriveFont on a font 10,000 times, and look at the memory consumption.
 * Since the derived fonts are being discarded little memory should be consumed. If too
 * much (determined empirically) has been consumed, report an error. Most likely cause
 * is a bad cache.
a little memory is consumed for 1.3.1_22-b03
Start : Memory used = 779848
Derive font : Memory used = 929824 change = 149976
----------System.err:(1/15)----------
STATUS:Passed.

but there is a real memory leak for 1.3.1_23-b01
Start : Memory used = 779832
Derive font : Memory used = 1590160 change = 810328
----------System.err:(10/507)----------
