Execute.setVMLauncher介绍

[英]Launch this execution through the VM, where possible, rather than through the OS's shell. In some cases and operating systems using the shell will allow the shell to perform additional processing such as associating an executable with a script, etc.
[中]在可能的情况下，通过VM而不是通过操作系统的外壳启动此执行。在某些情况下，使用shell的操作系统将允许shell执行附加处理，例如将可执行文件与脚本关联等。

/**
 * On VMS platform, we need to create a special java options file
 * containing the arguments and classpath for the java command.
 * The special file is supported by the "-V" switch on the VMS JVM.

 * @param exe the Execute instance to alter.
 * @param command the command-line.
