JDK-6958836 - javadoc should support -Xmaxerrs and -Xmaxwarns
Description
Using a user written doclet, 19 warnings were generated but no text stating "19 warnings".
Compile attached doclet.
run as

javadoc -package -doclet Field_Test3 \jdk170\src\java\lang\Thread.java

There are 4 warning. on previous builds it would print
"4 warnings"
at completion. 
This may be a side effect of the -Xmaxerrs/maxwarns implementation.
Comments
EVALUATION Yes, this is a side effect of the -Xmaxerrs/-Xmaxwarns work. As a side effect of that work, TWO Messager objects are created, an initial one to handle errors during option decoding, and a later one to handle errors from processing source code. Messager is responsible for printing the final counts (NOT JavaCompiler.compile2). In the case where no counts are output, the wrong messager is being used.

EVALUATION b99 is OK, b100 is not.

EVALUATION Fault reproduced. As an aside, it's easy to generate standalone API that creates warnings by using Sun propertietary API and getting that warning.
