A DESCRIPTION OF THE PROBLEM :
I found that javac with -cp does not work as excepted with jar wilcard *.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I made simple "Hello World" project (one class, package testing) using one JAR library (located at C:\Test\commons-lang-2.6.jar). In base directory (C:\Base) I made such command:

C\Base>javac -cp C:\Test\* testing\App.java

App,java is simple public class with classic public static void main, which uses one static method from
Commons Lang: org.apache.commons.lang,StringUtils.upperCase("test");.

After execution of above command I get such error:
javac: invalid flag: C:\Test\commons-lang-2.6.jar
Usage: javac <options> <source files>
use -help for a list of possible options

C:\Test dir contains 2 files: commons-lang-2.6.jar and commons-lang-2.6.pom




EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
compilation witohut error
ACTUAL -
compilation error

ERROR MESSAGES/STACK TRACES THAT OCCUR :
javac: invalid flag: C:\Test\commons-lang-2.6.jar
Usage: javac <options> <source files>
use -help for a list of possible options

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
package testing;

import org.apache.commons.lang.StringUtils;

}
}

CUSTOMER SUBMITTED WORKAROUND :
C\Base>javac -cp C:\Test\*; testing\App.java
C\Base>javac -cp .;C:\Test\* testing\App.java
C\Base>javac -cp .;C:\Test\commons-lang-2.6.jar testing\App.java
