/*
* 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.
