      Description

      FULL PRODUCT VERSION :


      A DESCRIPTION OF THE PROBLEM :
      With one jar file in the current directory, the classpath is allowed to set to *.jar without causing compilation error. And this jar file contains class(es) on which Test.java depends.

      "javac -classpath *.jar Test.java"

      However, if there are more than one jar file in the directory, compilation fails.

      This seems like a bug because according to Sun doc on classpath http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/classpath.html, the value of classpath should end with the name of a *.zip or *.jar for jar files. Furthermore, it doesn't make any sense to use wildcard, i.e. *.jar, when only one jar is allowed in the directory.


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      ---Test.java in workarea directory---
      import com.Print;

      public class Test {
          public static void main(String[] args) {
              Print p = new Print();
          }
      }

      ---Print.java in com directory---
      package com;

      public class Print { }


      Compile this file and then create a jar file:
      c:workarea\other\com>javac Print.java
      c:workarea\other\com>cd ..
      c:workarea\other>jar cvf pkg.jar com
      ---------------
      Place the pkg.jar into the workarea directory and compile Test.java.
      c:\workarea>copy .\other\pkg.jar .
      c:\workarea>javac -classpath *.jar Test.java

      No compilation error reported.

      --------------
      Put some jar files in the workarea directory and run the previous command again:
      c:\workarea>copy c:\jdk\jre\lib\deploy.jar .
      c:\workarea>javac -classpath *.jar Test.java

      Compilation fails.
      javac: invalid flag: pkg.jar
      Usage: javac <options> <source files>








      REPRODUCIBILITY :
