I'm a newbie in java application debugging, still, try to learn a various aspect of java application debugging. I have a windows application comprises of many jar file & executed by a single .exe file written in c++. The application works smoothly but after a certain time of usage, it crashes

(Java (TM) Platform SE binary is not responding)

leaving no log. I tried -XX:ErrorFile argument but it does not generate any error file. I have also tried heap-dump analysis but it also shows no memory leak. Can anyone please tell me what could be the possible reason for the JVM crash! Or how can I get the log file of the crash?

At the ideal time, the application consumes only 1-10% of CPU & 250-280MB Memory but after the crash, it sticks to 25% of CPU usage & 250-280MB Memory usage. I dedicated 2048M of Memory to this application.

Thread dump shows following thread before the application hang

"Thread-1" #12 daemon prio=5 os_prio=0 tid=0x0000000018392800 nid=0x2de0 waiting on condition [0x0000000018ece000]

After the application hang the same thread is changed to - 

"Thread-1" #12 daemon prio=5 os_prio=0 tid=0x0000000018392800 nid=0x2de0 in Object.wait() [0x0000000018ece000]

How can I solve the issue?

  • You should add more details what has happened. See https://stackoverflow.com/questions/44062332/jvm-crashes-when-calling-jni-function-during-gc – Martin Strejc Jun 30 '18 at 22:05
  • Thank you to trying to help me. Actually I don't know much details about java but I can send the file to you through mail or if possible DM. I can't share the link in public. – sks15 Jul 01 '18 at 04:03
  • "JVM crashes" is not the same as "JVM is not responding consuming 25% CPU (presumably 1 core)". – apangin Jul 01 '18 at 10:52
  • Obviously JVM did not crash - it seems to get into a busy loop. You need to find what it is busy with. Start with `jstack` or `jstack -m`. – apangin Jul 01 '18 at 10:56
  • I have done a thread dump but I actually don't know how to read it. If anyone please guide me where is the problem. Zip has both before & after the JVM crash. Here is the link of the thread dump [Link](https://www52.zippyshare.com/v/9wn0o7ii/file.html) – sks15 Jul 01 '18 at 16:49

    I don't see zip file at the link above - only lots of ads and malware. – apangin Jul 01 '18 at 21:38
