Description
The Java Console 'v' option to dump all threads' stacks does not work on Mac OS X due to differences in how the dynamic linker works on that platform compared to other Unix platforms. The libjvm.dylib already loaded by the current process can not be looked up via dlopen("libjvm.dylib").

EVALUATION Simplified the Java Console's stack dump code to use dlsym(RTLD_DEFAULT) rather than explicitly dlopen'ing libjvm.so. This simplifies the code on all Unix platforms and also makes it work on Mac OS X. Tested manually on Mac OS X and Solaris/x86. No test case because we do not test on Mac OS X.
