Class JDKVersionPrms

java.lang.Object

hydra.BasePrms

hydra.JDKVersionPrms

public class JDKVersionPrms
extends BasePrms

A class used to store keys for JDK version configuration settings. The settings are used to create instances of JDKVersionDescription. These can be referenced by instances of ClientDescription as configured using ClientPrms-jdkVersionNames.

The number of description instances is gated by names. For other parameters, if fewer values than names are given, the remaining instances will use the last value in the list. See $JTESTS/hydra/hydra.txt for more details.

Unused parameters default to null, except where noted. This uses the default, except where noted.

Values and fields of a parameter can be set to BasePrms.DEFAULT, except where noted. This uses the default, except where noted.

Values and fields of a parameter can use oneof, range, or robing except where noted, but each description created will use a fixed value chosen at test configuration time. Use as a task attribute is illegal.

Field Detail

names

public static Long names

(String(s)) Logical names of the JDK version descriptions. Each name must be unique. Defaults to null. Not for use with oneof, range, or robing.

javaHomes

public static Long javaHomes

(Comma-separated lists of String(s)) Java home directories used by hydra client JVMs configured to use this description. If supplied, values must be absolute paths to the Java home directory. Defaults to null, in which case the hydra client uses the Java home configured in its HostPrms.javaHomes. Otherwise, hydra starts a hydra client with the first Java home given. Each time the JVM is restarted, it uses the next Java home in its list. Once the last Java home is reached, the JVM stays with it for all further restarts.

This feature was put in place for tests that do rolling JDK upgrades. It is up to the test developer to use Java versions that are compatible with the corresponding product versions. For example, a product built with JDK 1.7 cannot run in a 1.6 JVM.
