Sorry for posting to the dev list rather than opening a jira, but my codehaus
credentials seem to be messed up somehow.
I tried running the 1.9 plugin on jdk 6 and got an exception like this:
at
org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:137)
... 20 more
Caused by: java.lang.NoSuchMethodError:
java.nio.CharBuffer.subSequence(II)Ljava/nio/CharBuffer;

org.codehaus.mojo.animal_sniffer.SignatureChecker.toSourceForm(SignatureChecker.java:471)
…
I think this is due to a change between java 6 and 7, subSequence is no longer
abstract:
package java.nio
[−] CharBuffer (2)
Change Effect
1 Abstract method CharBuffer.subSequence ( int p1, int p2 )became
non-abstract. Some methods in this class may change behavior.
2 Method CharSequence.subSequence ( int p1, int p2 ) has been overridden
by CharBuffer.subSequence ( int p1, int p2 ) Method CharBuffer.subSequence
( int p1, int p2 ) will be called instead of CharSequence.subSequence ( int p1,
int p2 ) in a client program.

This problem goes away if I compile trunk with jdk 6.
I've also been trying to use the ignores configuration property to exclude a
single class from analysis but I can't figure out any way to use it to
configure anything at all.
