[jira] [Updated] (GROOVY-7834) Calling hashCode on IntRange
iterates through all elements in the range.
[ https://issues.apache.org/jira/browse/GROOVY-7834?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
howard zhang updated GROOVY-7834:
---------------------------------
Description:
{code}
new IntRange(0, Integer.MAX_VALUE-1).hashCode()
{code}
The above code takes a few seconds to complete.
I believe the hashCode method is not overridden and it defaults to AbstractList which iterates through all elements. I don't think this should be the default behavior.

{code}
new IntRange(0, Integer.MAX_VALUE-1).hashCode()
{code}
