        Description

        Hi,

        we're seeing an -21.59% performance drop between s9u3_01 and s9u3_02 builds in Scimark benchmark, namely its sci_14_lrg2aServer_Monte metric.

        We believe it's due to the fact that Java Runtime Environment has changed between the named two builds.

        In s9u3_01 JRE was:
        Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_02-b02)
        Java HotSpot(TM) Server VM (build 1.4.0_02-b02, mixed mode)

        In s9u3_02 JRE was:
        Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
        Java HotSpot(TM) Server VM (build 1.4.1_01-b01, mixed mode)
