System.out.println lead to assert(resolved_method->method_holder()->is_linked()) failed: must be linked

Hi Coleen,

System.out.println was added on purpose:

Then it lead to the assertion error, similar as:

https://bugs.openjdk.java.net/browse/JDK-8069005

----- 8< -------- 8< -------- 8< -------- 8< -------- 8< -------- 8< ---

But just add java.lang.Object initialization in bootstrapping the jvm 
couldn't fix the issue:

diff -r 2c5bf37c8f8e src/hotspot/share/runtime/thread.cpp

Please give me some advice how to fix the issue, thanks a lot!
