JDK 7- Java control panel fails to launch on Solaris Sparc 9

JDK 7 Java control panel fails to launch on Solaris 9- Sparc (it is OK on Solaris 10 -Sparc).

It is a regression since JDK 7 - build 50 promotion.
* From b50 to b56: it throws Exception in thread /jre1.7.0/lib/sparc/libnio.so: ld.so.1: java: fatal: libc.so.1: open failed
* From b57 to current b59: it repeatedly throws exception "sun.font.NativeFont.getMapper(NativeFont.java:246)..."

Tested OS: Solaris 9- Sparc (ok with solaris 10-sparc)

Steps to reproduce:
------------------
1) On Solaris 9- sparc, install jre 7 -build 59
2) From the command line, launch jre 7 JCP /jre1.7.0/bin/ControlPanel

If you don't see JCP launched then the bug is reproducible

Detailed Exception:
------------------
1) b57 - b59: repeatedly exception thrown
at sun.font.NativeFont.getMapper(NativeFont.java:246)
...
...

2) b50 - b56
$ ./ControlPanel
