>
> Key: JCS-79
> URL: https://issues.apache.org/jira/browse/JCS-79
> Project: JCS
> Issue Type: Bug
> Components: Composite Cache
> Affects Versions: jcs-1.3
> Environment: java version "1.6.0_20"
> Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-9M3165)
> Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode)
> Reporter: Graham Leggett
> Assignee: Aaron Smuts
> Fix For: jcs-1.4-dev
>
>
> When an attempt is made to use torque's JCS support, JCS crashes on
> initialisation with a NullPointerException as below.
> The cause is that CompositeCacheConfiguration.parseRegion is passed a
> parameter called "value", and this value is not guarded against being null.
> The failure happens on this line:
> StringTokenizer st = new StringTokenizer( value, "," );
> If value is a required string, a proper error message explaining exactly what
> the problem is, and exactly what the end user must do to fix it should be
> thrown.
> Looking further, the "value" comes from this field in CompositeCacheManager:
> /** The default auxiliary caches to be used if not preconfigured */
> protected String defaultAuxValues;
> This field is given no default value, and no documentation exists explaining
> how an end user might populate this value, or what the significance of this
> value is.
> The full stack trace looks like this:
> Caused by: java.lang.NullPointerException
> at java.util.StringTokenizer.<init>(StringTokenizer.java:182)
> at java.util.StringTokenizer.<init>(StringTokenizer.java:204)
