| * 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. |
