+ * This test consists of two scenarios:
+ *
+ * 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.
