The following regression test fails with fastdebug or fastdebug1 builds
on Solaris :-
    test/java/nio/channels/spi/SelectorProvider/inheritedChannel/run_tests.sh

Attached is a sample hs_err file showing the crash. The crash stems from a
build issue with the mini-launcher used by the test. Specifically the
launcher is using fork to create launch the service under test and this
interrupts all threads leading to obscure failure modes. In product
mode assertions are disabled and hence the failure has not been observed
or reported.

Trivally fixed by re-compiling the launcher with __solaris__ defined.
