STEPS TO REPRODUCE:

1. download jdk 10 build 36 from artifactory to install on mac machine.
2. set JAVA_HOME and PATH to refer to jdk 10 build 36 accordingly.
3. download the attachment "explodedmodulestest.zip" from bug.
4. extract the zip which results in explodedmodulestest folder and navigate to explodedmodulestest folder in command line.
5. execute the following commands at command line.

compile:
javac -d . JavaApiExplodedModulesTestInJDK10MAC.java

execution:
java testapps.JavaApiExplodedModulesTestInJDK10MAC

ISSUE: Look for the String which follows after "Return value of execute is" in the above output.
JDK 10 BUILD 35 returns the folder path.
JDK 10 BUILD 36 returns null.
