PI_DO_NOT_REUSE_PUBLIC_IDENTIFIERS_CLASS_NAMES message missing substitutions

I'm seeing messages like the following from Spotbugs 4.8.0:

M B PI_DO_NOT_REUSE_PUBLIC_IDENTIFIERS_CLASS_NAMES PI: Class name ?>?1/1??? in source file ?>?2/1??? shadows the publicly available identifier from the Java Standard Library. In Clock.java

Presumably this is meant to print an actual class name and file path rather than ?>?1/1??? and ?>?2/1???
