I understand,
"Islands of Isolation" means objects pointing to each other, without any live threads accessing any of these objects.
Is that correct?

Are these objects forming "islands of isolation" eligible for GC?

Yes they are, Actually this is the only case in which objects becomes eligible for garbage collection even if they still have valid references.

that means all these objects will be garbage collected, when JVM does the garbage collection?

There are no guarantees if the objects will be garbage collected. You just need to know that they are eligible for GC for SCJP...
