A system and a method for loading a called class file table with data indicating a highest version of a class file of a software application are provided. The method includes retrieving a first class version dependency file associated with a first class file, having both a first class name and a first version number associated with a second class file that is called by the first class file. The method further includes adding a first record to the called class file table having both the first class name and the first version number associated with a second class file, and retrieving a second class version dependency file associated with a third class file. The second class version dependency file has both a second class name and a second version number associated with a fourth class file called by the third class file. The method further includes if the second class name is identical to the first class name in the called class file table and the second version number is higher than the first version number, then updating the first record in the called class file table with the second class name and the second version number.
