      JVM 1.4.2 (client) has a regression on Sierra EE RC4 startup compared to JVM 1.3.1 with default HotSpot options: 34.56 sec vs 28.47 sec of total user CPU time (21% regression) and compared to JVM 1.4.1: 34.56 sec vs. 32.53 sec (6% regression). Regression in C++ function Compilation::compile_java_method() was observed.
      To reproduce:
      -Install JDK 1.3.1
      -Install Sun ONE Studio Sierra EE 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 1.4.2 with the latest libjvm.so
      -Install Sun ONE Studio Sierra EE using Installer with JDK 1.4.2
      -Run command: /bin/time <sierra_with_jdk1.4.2_install_path>/bin/runide.sh -J-Dnetbeans.close=true
      Note: second and following startups were always measured.
