Hi Igor,

the fix looks good to me. Should we add --debug to our testing?

The problem is that HotSpotCompiledCodeBuilder.createCompiledCode() assumes that if its method argument is null it’s a stub. And stub always has a name. The absence of a name caused the crash later on in the C++ code in CodeInstaller::install().
