For this input log file:

<log>
First for Ant javac or pure javac

[javac] D:\path\to\my\Class.java:225: warning: [deprecation] loadAvailable(java.lang.String,int,int,java.lang.String[]) in my.OtherClass has been deprecated
[javac] oc.loadAvailable("roottest.xml", 0xFFF, 0xFFFF, new String[]

{"filter"}

);
[javac] ^

Then for maven javac

[WARNING] D:\path\to\my\Class.java:[225,39] [deprecation] loadAvailable(java.lang.String,int,int,java.lang.String[]) in my.OtherClass has been deprecated
</log>

we expect the category to be 'Deprecation' but we get 'Deprecation] loadAvailable(java.lang.String,int,int,java.lang.String[' instead.
