-------------------------------------------
Summary: Ensure no Numbers arguments are passed to
MessageFormat.format in Lucene/Solr
Key: SOLR-7258
URL: https://issues.apache.org/jira/browse/SOLR-7258
Project: Solr
Issue Type: Task
Reporter: Shalin Shekhar Mangar
Assignee: Shalin Shekhar Mangar
Fix For: 5.1
While tracing some TestBlobHandler failures with the thai locale I found that
the problem was MessageFormat.format which when given a Number ultimately
executes NumberFormat.getInstance(getLocale()).format(argument). In thai
locale, this transforms the digit 1 to a thai character and hence fails the
test.
We should audit all usages of MessageFormat.format to see if any Number objects
are being passed as argument and wrap them with String.valueOf().
I don't think forbidden-api can catch such problems. Perhaps we just forbid
MessageFormat.format itself?
