Michael Miklavcic reassigned METRON-614: ---------------------------------------- Assignee: Michael Miklavcic > Eliminate use of the default Charset > ------------------------------------ > > Key: METRON-614 > URL: https://issues.apache.org/jira/browse/METRON-614 > Project: Metron > Issue Type: Bug > Reporter: Justin Leet > Assignee: Michael Miklavcic > Priority: Minor > Time Spent: 8h 40m > Remaining Estimate: 0h > > During work on METRON-612, I noticed a lot of our warnings are from implicit > use of the default Charset (e.g. when creating InputStreamReaders). Given > that this value is platform dependent, we should at least consider explicitly > using a particular Charset. > In addition, after fixing this, I would like to see it upgraded to a compile > error, because in my experience almost everyone tends to use methods that use > the implicit default Charset. This can be done by changing the compiler arg > in the pom to instead be > {code} > <compilerArgs> > <arg>-Xlint:unchecked</arg> > <arg>-Xep:DefaultCharset:ERROR</arg> > </compilerArgs> > {code} > My assumption is that we'll want UTF-8, but given a lack of expertise and > that usually there's a lot of opinions on character set issues, we may want > to consider other options. > http://errorprone.info/bugpattern/DefaultCharset > https://docs.oracle.com/javase/8/docs/api/java/nio/charset/Charset.html lists > standard Charsets and provides more details. > {code} > Charset Description > US-ASCII Seven-bit ASCII, a.k.a.
