* Flowchart of launcher execs and options processing on unix |
|
80 |
* |
|
81 |
* The selection of the proper vm shared library to open depends on |
|
82 |
* several classes of command line options, including vm "flavor" |
|
83 |
* options (-client, -server) and the data model options, -d32 and |
|
84 |
* -d64, as well as a version specification which may have come from |
|
85 |
* the command line or from the manifest of an executable jar file. |
|
86 |
* The vm selection options are not passed to the running |
|
87 |
* virtual machine; they must be screened out by the launcher. |
|
88 |
* |
|
89 |
* The version specification (if any) is processed first by the |
|
90 |
* platform independent routine SelectVersion. This may result in |
|
91 |
* the exec of the specified launcher version. |
|
92 |
* |
|
93 |
* Now, in most cases,the launcher will dlopen the target libjvm.so. All |
|
94 |
* required libraries are loaded by the runtime linker, using the known paths |
|
95 |
* baked into the shared libraries at compile time. Therefore, |
|
96 |
* in most cases, the launcher will only exec, if the data models are |
|
97 |
* mismatched, and will not set any environment variables, regardless of the |
|
98 |
* data models. |
