================================================================================================

Problem Suspect 1 One instance of java.util.concurrent.LinkedBlockingQueue loaded by <system
class loader> occupies 79,698,088 (92.41%) bytes. The top consumers of its minimum retained heap
are byte[] (152 instances totaling 79,694,208), java.util.concurrent.LinkedBlockingQueue$Node
(153 instances totaling 3,672), and java.util.concurrent.locks.ReentrantLock$NonfairSync (2
instances totaling 64). The instance is referenced by
com.ankurm.oomdemo.UnboundedQueueLeakApplication$$Lambda+0x000000000b25d428 @ 0xf63bb570 ,
loaded by org.springframework.boot.loader.launch.LaunchedClassLoader @ 0xf631bab8 . The memory
is accumulated in one instance of java.util.concurrent.LinkedBlockingQueue$Node , loaded by
<system class loader> , which occupies 1,572,984 (1.82%) bytes. Thread java.lang.Thread @
0xfcc19e38 main has a local variable or reference to java.util.concurrent.LinkedBlockingQueue @
0xff7386e8 which is on the shortest path to java.util.concurrent.LinkedBlockingQueue$Node @
0xfccce5c0 . The thread java.lang.Thread @ 0xfcc19e38 main keeps local variables with total size
632,832 (0.73%) bytes. The top consumers of its minimum retained heap are byte[] (152 instances
