Using 64bit VM settings, min.heap=1024MB, min permgen=256MB, default fork arguments=[-Xmx1024m, -XX:MaxPermSize=256m]

If you have just closed any java program then wait for a few minutes and give chance to garbage collection to remove the unwanted space and clean the Heap memory.

sun.misc - cannot be resolved | AEM Bundle

sun.misc -- Cannot be resolved but is not required and overwritten by Boot Delegation

Resolution

This error we see sometimes while installing bundle in Adobe Experience Manager(AEM). If you are seeing this error just after the installation of the package then wait for a few minutes to resolve the dependencies. Most of the time it will resolve automatically as soon as the dependent library or service will available. After a few minutes if this is not getting resolved then check your POM and ensure you are adding the correct dependency which is available in the system.
