Reporting org-babel bug for java

Hello,

I've never used a mailing list before, so bear with me if I'm not "doing
this right."

I found behavior that I think is a bug and not a feature. This is for
org-babel Java.

The content below the equals signs, below, comprise an org-mode file that I
will refer to in order to report the behavior that is the topic of this
post. Two Java jars are referenced in the classpaths and are needed in
order to run the code. They can be obtained from the Junit download page.

This code basically runs a Junit test. The concern I have is with this line:

#+begin_src java :classname ParameterizedTest :cmpflag "-cp
~/Linux/rep/junit-4.12.jar:~/Linux/rep/hamcrest-core-1.3.jar:." :cmdline
"-cp ~/Linux/rep/junit-4.12.jar:~/Linux/rep/hamcrest-core-1.3.jar:."

If I press C-c C-c on this block of code, it runs fine. However, if the
string after :cmpflag is written as "-cp
.:~/Linux/rep/junit-4.12.jar:~/Linux/rep/hamcrest-core-1.3.jar" the
compilation of this Java class will fail because the Junit jar cannot be
located!

This only happens because I change the order of the jars as they appear in
the classpath. This is not a Java problem, since the order of items in the
classpath should not change Java behavior. I have to conclude there is
something happening in the org-babel code that is causing this.


Org-mode file below
