58 |
* options which specify the version are not passed to the exec'd version,

* to suppress the version selection code. This is not only for efficiency,

* but also for correctness, since any command line options have been
|

63 |
* removed which would cause any value found in the manifest to be used.
|

* This would be incorrect because the command line options are defined
|

65 |
* to take precedence.
|
|
66 |
*
|
|
67 |
* The value associated with this environment variable is the MainClass

* name from within the executable jar file (if any). This is strictly a
|
|
69 |
* performance enhancement to avoid re-reading the jar file manifest.
