* This test consists of two scenarios:
|
|
*
|
|
* Scenario A: create a jar with entries exceeding 64K, and see if the javac
|
|
* can handle this large jar on the classpath. Generally this test completes
|
|
* within a minute
|
|
*
|
|
* Scenario B: create a jar with a large enough file exceeding 4GB, and
|
|
* similarly test javac. This test is known to be slow and problematic on
|
|
* certain operating systems, thus this test can be selected by passing a
|
|
* property through jtreg as follows:
|
|
* -javaoptions=-DT6836682.testScenarioB=true.
|
|
* Note this test will only run iff all the disk requirements are met at runtime.
