      JVM 1.4.1 (client) has a regression on Sierra EE RC4 startup compared to JVM 1.3.1 with default HotSpot options: 32.53 sec vs 28.47 sec of total user CPU time (14% regression). Collector's experiments indicate that there is regression in dynamic compilation time of HotSpot, more specifically, most of the regression can be attributed to a C++ function Compilation::compile_java_method(): 4.7 sec vs 1.7 sec (180% regression).
      To reproduce:
      -Install JDK 1.3.1
      -Install Sun ONE Studio Sierra Release Candidate 4 using Installer with JDK 1.3.1
      -Run command: /bin/time <sierra_with_jdk1.3.1_install_path>/bin/runide.sh -J-Dnetbeans.close=true
      -Install JDK 1.4.1
      -Install Sun ONE Studio Sierra Release Candidate 4 using Installer with JDK 1.4.1
      -Run command: /bin/time <sierra_with_jdk1.4.1_install_path>/bin/runide.sh -J-Dnetbeans.close=true
      Note: second and following startups were always measured.
