|
|
* Scenario A: create a jar with entries exceeding 64K, add a main class and

|
* see if the launcher can handle it.
|
|
*
|
|
* Scenario A1: create a jar as in A, but add a zipfile comment as well.
|
|
*
|
|
* Scenario B: create a jar with a large enough file exceeding 4GB, and
|
|
* similarly test the launcher. This test can be run optionally by using the
|
|
* following jtreg option:
|
|
* "-javaoptions:-DBigJar_testScenarioB=true"

* or set
|
|
* "BigJar_testScenarioB" environment variable.

* Note this test will only run iff all the disk requirements are met at runtime.
