763 |

|
764 |
* the old process. Therefore, any processes waiting on the initial
|
|

* process wake up and they shouldn't. Hence, a chain of pseudo-zombie
|

766 |
* processes must be retained to maintain the proper wait semantics.
|

* Fortunately the image size of the launcher isn't too large at this
|
|
768 |
* time.
|
|
769 |
*
|

* execv(path, argv);

*
|
|
778 |
* exit((int)spawnv(_P_WAIT, path, argv));
|
|
779 |
*

* Unfortunately, a bug in Windows spawn/exec impementation prevents
|
|
781 |
* this from completely working. All the Windows POSIX process creation
|
|
782 |
* interfaces are implemented as wrappers around the native Windows
|
|
783 |
* function CreateProcess(). CreateProcess() takes a single string
|
|
784 |
* to specify command line options and arguments, so the POSIX routine
|
|
785 |
* wrappers build a single string from the argv[] array and in the
|
|
786 |
* process, any quoting information is lost.
|
|
787 |
*
|
|
788 |
* The solution to this to get the original command line, to process it
|
|
789 |
* to remove the new multiple JRE options (if any) as was done for argv
|
|
790 |
* in the common SelectVersion() routine and finally to pass it directly
|
|
791 |
* to the native CreateProcess() Windows process control interface.
