explicitly.
If there is custom class loader and custom security manager then they
are loaded/initialized before the main class is loaded. Ditto for tool
agents specified on the command line or in the manifest as they are also
loaded/initialized before the main class.
If the main class has an initializer then it won't normally run. I say
"normally" because the custom class loader or an agent could be in
cahoots with the main class and cause it to initialize before the
launcher invokes the "main" method. My personal view is that this is way
too much detail to attempt to capture in the brief description that is
the usage message. I think we have to assume that the usage will be read
by non-experts. So no issue with adjusting the message to make it
clearer but we should limit it to a few lines. Here is the current output:
--dry-run create VM and load main class but do not execute main
method.
This --dry-run option may be useful for validating the
command-line options such as the module system
configuration.
"This --dry-run" should be "The --dry-run" but otherwise it seems a
reasonable summary of what this option does.
