-------------------------------------------------------------

[^forbiddenapis.out] Results for source classes.
{noformat}
Search "Forbidden method invocation" (362 hits in 1 file)
Search "Forbidden class/interface use" (79 hits in 1 file)

Search "Deprecated in Java 1.8" (9 hits in 1 file)
Search "[Uses default charset]" (73 hits in 1 file)
Search "Uses default locale" (237 hits in 1 file)

Search "Reflection usage to work around " (44 hits in 1 file) 
Search "[non-portable or internal runtime class]" (74 hits in 1 file)
{noformat}
I think the number of errors (locale + charset + deprecated) are not very 
large, and I can fix them, if asked to? [~elserj] is already taking care of 
around ~50 of them.
 Also I had a look at several projects using forbiddenapis, none of them were 
banning jdk-non-portable and jdk-reflection. Do we need to ban it?

> [Policeman's Forbidden API 
> Checker|https://github.com/policeman-tools/forbidden-apis] provides an 
> elegant way to fail build if any "forbidden api" is used in the code base.
> Here we will add the plugin to our pom.xml.
> We will discuss which all api's to put in forbidden list. Or whether to use 
> the one's bundled with the plugin.
