EVALUATION

Times for the test above:
    jdk1.6u34:  222ms
    jdk1.7u04: 2948ms
    jdk1.7u06:  681ms

Seems, I found a way to improve performance more.
                                     

EVALUATION

The fix increases performance up to 3 times, making it still 3 times worse than it was before the regression

I used the code below for verification

public class PropertyDescriptorTest {
    public static void main(String[] args) throws Exception {
        long starttime = System.nanoTime();
        for (int i = 0; i < 10000; i++) {
            new PropertyDescriptor("name", PropertyDescriptor.class);
        }
        long time = System.nanoTime() - starttime;
        System.err.println(time/1000000);
    }
}
                                     

EVALUATION

The situation described above confirmed on another host (another platform). Fixed build still shows 3 times performance loss compared to 1.6 release.

Closing as Fixed failed
                                     

EVALUATION

Backporting to JDK 7. See details in the main CR.
