Reverting to the Previous Version of the JRE

Note: For 3.3.1, you cannot revert to an older version of Java.

To revert to a previous version of the JRE, invoke the tool with the intended JRE_HOME as argument.
```
update -jreHome <path>
```
Note: You cannot use this command to revert to an externally installed version of JRE 1.6. For that, you must use the "update -jreHome TIBCO_JRE" command.
To revert to tibcojre, specify TIBCO_JRE as the value for the argument -jreHome.
```
update -jreHome TIBCO_JRE
```
