DESCRIPTION:
The format of the String returned by sun.rmi.rmic.BatchEnvironment.createClassPath() changed at 1.6.0_01 and 1.5.0_11, probably as a result of the fix for CR 6473331.

In the 1.6.0 GA release, and 1.5.0_10 and earlier, the output looks like this:

C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\resources.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\rt.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\sunrsasign.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\jsse.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\jce.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\charsets.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\classes;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\ext\dnsns.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\ext\localedata.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\ext\sunjce_provider.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\ext\sunmscapi.jar;C:\builds\sun\jdk6.0\jdk-6-fcs-bin-b105-windows-i586-29_nov_2006\jdk6\jre\lib\ext\sunpkcs11.jar;.

Whereas in 1.6.0_01 and later, and 1.5.0_11 and later, the output looks like this:

Note that the semicolon separators ';' have been replaced by backslashes '\'. The same problem occurs on Solaris and Linux, with forward slashes '/' in place of the correct colon ':' separator.

This change has serious consequences for one of our product groups and needs to be addressed as soon as possible.

TESTCASE SOURCE:

Note that the following testcase needs to be compiled and executed with [JAVA_HOME]\lib\tools.jar on the classpath.

----------------------------------------------------------------------
import sun.rmi.rmic.*;

public class ClassPathTest {
    public static void main (String args[]) {
        System.out.println(sun.rmi.rmic.BatchEnvironment.createClassPath(null, null, null));
    }
}
