      Description

      JRE 5.0 Update 17 encounters quickly java.lang.OutOfMemoryError,
      when opening zip files in a loop.

      The issue is quite easily reproducible on JRE 5.0 by running the following
      testcase.

      1. Testcase
      -----------
      The testcase consists of the following files:

        3462 Apr 15 09:59 ZipFileRepeatOOM.java
      139659 Apr 15 09:59 longEntries.zip

      The zip file "longEntries.zip" is opened over and over after renaming it in
      every iteration.

      2. Compile
      ----------
      /jdk1.5.0_17/bin/javac ZipFileRepeatOOM.java

      3. Run
      ------
      3.1 Client VM
      -------------
      % mv longEntries.zip_<nn> longEntries.zip
      % /jdk1.5.0_17/bin/java -client -Xms64m -Xmx64m -XX:MaxPermSize=32m -DresultCount=0 ZipFileRepeatOOM longEntries.zip
      Set input file specification to "longEntries.zip"
