    Description


      ###@###.### 2002-08-13

      J2SE Version (please include all output from java -version flag):
       java version "1.4.1-beta"
       Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-beta-b18)
       Java HotSpot(TM) Client VM (build 1.4.1-beta-b18, mixed mode)

      Does this problem occur on J2SE 1.3 or 1.4?
      In 1.4.01

      Operating System Configuration Information (be specific):
       Windows 2000 Proffesional, Service Pack 2, Czech locale

      Hardware Configuration Information (be specific):
       IBM Thinkpad A21m, 320MB RAM

      Bug Description:
       Few moments after program startup client VM begins
       to allocate massive amounts of memory which leads
       to total exhausting of system virtual memory.

      Note:
       Problem can be switched on/off in the file GraphOfDependencies.java:
       If LinkedHashMap is instantiated in constructor, all is OK. If on
       line 87, bug appears.

      Steps to Reproduce (be specific):

      >javac GraphOfDependencies*.java TestGOD2.java
      >java TestGOD2.java

      Erro dialog box popup: "Your system is low on virtual memory...."

      Uncomment LinkedHashMap(line 87), exhausting of system virtual memory not happen.
