zero broken in jdk/jdk?

[Magnus Ihse Bursie]

I get the following build error when building zero in jdk/jdk:

workspace/build/linux-x64-zero/hotspot/variant-zero/libjvm/objs/os_linux.o: 
In function `os::abort(bool, void*, void const*)':
workspace/open/src/hotspot/os/linux/os_linux.cpp:1358: undefined 
reference to `ClassLoader::close_jrt_image()'
collect2: error: ld returned 1 exit status
lib/CompileJvm.gmk:172: recipe for target 
'workspace/build/linux-x64-zero/support/modules_libs/java.base/server/libjvm.so' 
failed

Is this a known problem?
