             Summary: Elytron MatchRule.toString() method throws StringIndexOutOfBoundsException
                 Key: ELY-1078
                 URL: https://issues.jboss.org/browse/ELY-1078
             Project: WildFly Elytron
          Issue Type: Bug
            Reporter: Ondrej Lukas
            Assignee: Darran Lofthouse
            Priority: Critical


In case when implementation of {{asString(StringBuilder b)}} for MatchRule does not change length of passed parameter (which is 0) then 'java.lang.StringIndexOutOfBoundsException: String index out of range: -1' is thrown for calling {{MatchRule.toString()}} due to calling {{StringBuilder.setLength(-1)}}. 

e.g. MatchRule {{ALL}} in implementation {{asString(StringBuilder b)}} just returns passed parameter, which results to mentioned exception. 

Thrown exception:
{code}
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
	at java.lang.AbstractStringBuilder.setLength(AbstractStringBuilder.java:180)
	at java.lang.StringBuilder.setLength(StringBuilder.java:76)
	at org.wildfly.security.auth.client.MatchRule.toString(MatchRule.java:581)
    ...
{code}
