        The value of full_count in the message of insufficient codecache is 0 even though a codecache shortage occurred.
        full_count is the number of times the code heap was full.
        This issue is common to all operating systems.

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        javac WasteCodeCache.java
        java -XX:ReservedCodeCacheSize=2496k -XX:-UseCodeCacheFlushing WasteCodeCache

        EXPECTED OUTPUT :
