>                 Key: TOMEE-976
>                 URL: https://issues.apache.org/jira/browse/TOMEE-976
>             Project: TomEE
>          Issue Type: Bug
>    Affects Versions: 1.5.2
>         Environment: Virtual server in larger Solaris box - returns 236 availableProcessors (Runtime.getRuntime().availableProcessors())
>            Reporter: Henning Kristensen
>             Fix For: 1.7.0

> "part" gets rounded to 0 at line 189 in org.apache.tomee.catalina.Warmup.java when there's more than double the number of availableProcessors compared to the number of classes to preload. Subsequently the server doesn't start properly.
> I would think that "part" should be guarded against being 0.
