      Description

      FULL PRODUCT VERSION :
      1.6.0_02

      ADDITIONAL OS VERSION INFORMATION :
      Windows XP 5.1.2600

      A DESCRIPTION OF THE PROBLEM :
      I have one class repository in my network with about 30,000 classes, all in same package. This repository is used as a network mapped drive in all developers machines. The network works at 100mbps. Everything works fine until now, when I am testing java 6. Currently we are using javac 1.4, and compilation takes about 20 seconds. But with javac 6.0, its taking about 2 minutes.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      One package with about 30,000 classes in some network mapped drive.
      Put this network mapped drive in classpath.
      Compile one class that depends from some of that classes.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Compilation taking about 20 seconds as in javac 1.4.2.

      ACTUAL -
      Compilation takes about 2 minutes in javac 6.0

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      No error messages.

      REPRODUCIBILITY :
      This bug can be reproduced always.

      Release Regression From : 1.4.2
      The above release value was the last known release where this
      bug was not reproducible. Since then there has been a regression.
