When a conditional compile argument is missing, compiler error is not generated if application cache is turned on.

Steps to reproduce:
1. Compile attached test cases using:

javac -classpath <path to flex-compiler-oem.jar> OEMTest.java

2. Run using:

java -cp .:<path to flex-compiler-oem.jar> OEMTest

Actual Results:

Expected Results:

Workaround (if any):
comment application cache.. comment the two lines in the java file.
