 /*
  * 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.
