Subject [PATCH] PatternSyntaxException in MailboxQuery
Date Tue, 13 Jan 2015 15:53:11 GMT
Hi all,

I encountered a bug in the MailboxQuery class, posted as the following 
ticket: https://issues.apache.org/jira/browse/JAMES-1566 . It occures 
for folder names which contain unclosed parentheses (like 
"Folder.foo(bar") and will raise the following exception:

java.util.regex.PatternSyntaxException: Unclosed group near index 13
Folder.foo(bar
                         ^

A possible workaround is to always treat the whole folder name literally 
and only replace the wildcard characters. I made a patch which should 
solve the problem.

Best regards
Thomas
