Hi Ivan,

I'm not sure if it is related to JDK-8008759 which has been fixed in 8. 
That one is also related
to the fastdebug binaries, though the issue is more like other native 
code calls into jdk zlib code.

As far as I'm aware of those versions of Solaris jdk/jre should be 
statically linked with our own
zlib library, it is hard to image that it starts to call a native 
platform zlib.

Have you run the test version of jdk/jre with your patch in the similar 
testing environment?
Though the patch looks harmless.
