Henning Kristensen created TOMEE-976:
----------------------------------------
Summary: Server startup fails on large, virtual Solaris servers
with java.lang.ArithmeticException: / by zero
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
"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.
Here's the top of the startup log:
