[dna-issues] [JBoss JIRA] Resolved: (DNA-526) IllegalStateException calling TokenStream.canConsume(String str) after consuming all tokens via canConsume(String[])

IllegalStateException calling TokenStream.canConsume(String str) after consuming all tokens via canConsume(String[]) -------------------------------------------------------------------------------------------------------------------- Key: DNA-526 URL: https://jira.jboss.org/jira/browse/DNA-526 Project: DNA Issue Type: Bug Components: Common Affects Versions: 0.7 Reporter: Barry LaFond Assignee: Barry LaFond Fix For: 0.7 Attachments: dna-common_DNA_526.patch While parsing, I wished to call canConsume() for multiple "optional" properties. Some are "multi-string" using canConsume("xxxx", "xxxx", ....) If a previous canConsume() had finished parsing the tokens (i.e. currentToken == NULL), then a subsequent canConsume("xxxx") would result in the following exception: java.lang.IllegalStateException: The 'start()' method must be called before tokens can be consumed or matched at org.jboss.dna.common.text.TokenStream.currentToken(TokenStream.java:1160) at org.jboss.dna.common.text.TokenStream.matches(TokenStream.java:866) at org.jboss.dna.common.text.TokenStream.canConsume(TokenStream.java:609) at .... It appears that the canConsume( <MULTIPLE> ) methods do NOT call moveToNextToken() which is currently the only method that sets this.completed = TRUE. Fix would be to add: this.completed = this.currentToken == NULL before returning on the canConsume( <MULTIPLE> ) methods.
