Java Version: 1.7.0-b124
Platform: windows Vista

Problems:
In b124 promotion testing, there is a test called FontStyleTest failed by threw exceptions.
The exception threw when display font name "High Tower Text" with style isBold as below:

Test is PASS:  Font Name: Harrington Font Style: isItalic
Test is PASS:  Font Name: Harrington Font Style: isPlain
Test is PASS:  Font Name: Harrington Font Style: isBold
Test is PASS:  Font Name: Harrington Font Style: isItalic
Test is PASS:  Font Name: High Tower Text Font Style: isPlain

FontStyleTest is: FAIL
Exception thrown

since the font size is randomly generated, we don't know exactly size caused the exception.

Please find the original testcase in attachment section, and a modified standalone testcase as following, but I cannot reproduce the exceptions in windows vista with the test case, file a bug for record to trace this problem.
