>Description:
Starting up tomcat-7 with additional debug flags: "-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n" results in:

/usr/local/openjdk7/jre/lib/amd64/libnpt.so: Undefined symbol "libiconv_open"

Sure enough:

8:53pm> nm /usr/local/openjdk7/jre/lib/amd64/libnpt.so | grep iconv 
0000000000002070 t iconvConvert
                 U libiconv
                 U libiconv_close
                 U libiconv_open

This is because I also have libiconv installed, and openjdk/jdk/src/solaris/instrument/EncodingSupport_md.c is including /usr/local/include/iconv.h instead of /usr/include/iconv.h during compilation from its: #include <iconv.h> directive.
>How-To-Repeat:
Install libiconv.
Build java/openjdk7
>Fix:
A workaround is to shift /usr/local/include/iconv.h out of the way during the build (and restore once complete).

A possible fix would be to patch EncodingSupport_md.c to force it to use the base system's iconv.h during post-patch?
