the class Invoker method invokeUnchecked.

Example 2 with InnocuousThread

use of jdk.internal.misc.InnocuousThread in project Bytecoder by mirkosertic.

the class CleanerImpl method run.

/**
 * Process queued Cleanables as long as the cleanable lists are not empty.
 * A Cleanable is in one of the lists for each Object and for the Cleaner
 * itself.
 * Terminates when the Cleaner is no longer reachable and
 * has been cleaned and there are no more Cleanable instances
 * for which the object is reachable.
 * <p>
 * If the thread is a ManagedLocalsThread, the threadlocals
 * are erased before each cleanup
