[infinispan-issues] [JBoss JIRA] (ISPN-7566) ByteString.readObject() throws NegativeArraySizeException when length > 127

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-7566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13531711#comment-13531711 ] 

Paul Ferraro commented on ISPN-7566:
------------------------------------

Is the enforcement of a byte length really necessary?  The hibernate 2nd level cache code can easily generate cache names with byte arrays larger than 127.  Why not instead use https://github.com/infinispan/infinispan/blob/master/commons/src/main/java/org/infinispan/commons/io/UnsignedNumeric.java ?

> We don't expect or recommend cache names this big, but we should fail at the time the `ByteString` is created and not at the time it is read by a remote node.
