      Verified

      Description

      FULL PRODUCT VERSION :
      java version "1.7.0_03"
      Java(TM) SE Runtime Environment (build 1.7.0_03-b05)
      Java HotSpot(TM) Client VM (build 22.1-b02, mixed mode, sharing)

      REGRESSION. Last worked in version 6u29

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Script (batch file) for running the test:

      mkdir lib
      javac test/*.java
      jar cvf lib/a.jar test/A.class
      jar cvf lib/b.jar test/B.class
      java -cp "lib/*" test.B


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Following message should be on the output:

      main() in class B executed

      ACTUAL -
      Following message appears on the output:

      Error: Could not find or load main class lib.b.jar

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      File test/A.java:
      ---
      package test;

      class A {
      }
      ---

      File test/B.java:
      ---
      package test;

      class B {
          public static void main(String[] args) {
              System.out.println("main() in class B executed");
          }
      }
      ---

      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Command line for executing the code must be modified e.g. like following:

      java -cp "lib/*;" test.B

      Please note that instead of "*" is there "*;". Then execution works as expected.
