Problem is a generic term for an error or warning.
Each problem has a default severity classifying it as
CompilerProblemSeverity.ERROR
,
CompilerProblemSeverity.WARNING
, or
CompilerProblemSeverity.IGNORE
.
The severity of any problem can be changed
from the default setting by compiler options.
Ignored problems are simply not reported by clients.
Every problem class has an English DESCRIPTION
field.
This field can use named placeholders such as ${className}
;
the value of the corresponding field in the problem object is substituted
when the problem is displayed.
An English Java .properties
file gets built from the
DESCRIPTION
fields and then localized.
