We've upgraded to 7u21 and now we're seeing the same initialization problem as
reported in bug JDK-8002283, except this time with WeakHashMap instead of
HashMap. The same workaround of explicitly initializing WeakHashMap in
System.initializeSystemClass has gotten us around the issue.
Here's the stack trace.
