| * The test creates a jar file with more than 64K entries. The jar file is |

| * |
| * The aim is to verify classes included in jar files with more than 64K entries |
| * created with Java 6 can be loaded by more recent versions of Java. |
| * |
| * A path to JDK or JRE version 6 is needed. This can be provided |
| * by passing this option to jtreg: |
| * -javaoption:-Djava6.home="/path/to/jdk_or_jre6" |
