The JVM uses SIGQUIT to perform thread dumps. Applications embedding the JVM frequently need to trap signals such as SIGINT or SIGTERM, which can lead to interference with the JVM signal handlers. The -Xrs option is available to address this issue. When -Xrs is used, the signal masks for ...
When -Xrs is used, the signal masks for SIGINT, SIGTERM, SIGHUP, and SIGQUIT aren’t changed by the JVM, and signal handlers for these signals aren’t installed. Windows: The JVM watches for console control events to implement shutdown hooks for unexpected termination. Specifically, the ...

As ckhan mentioned,jstackis great because it gives the full stack trace of all active threads in the JVM. The same can be obtained on stderr of the JVM using SIGQUIT. Another useful tool isjmapwhich can grab a heap dump from the JVM process using the PID of the process: jmap -dump:...
The next line describes the signal type, program counter (pc) that caused the signal, process ID and thread ID, as follows. Copy Copied to Clipboard Error: Could not Copy # SIGSEGV (0xb) at pc=0x417789d7, pid=21139, tid=1024 | | | | +--- thread id | | | +--- process id ...
• WorldPreview 5.0.0 for 1.14.4 is now allowed. This update brings water transparency, fixes reliability issues with the quit button on preview, and tries to address xraying with the first chunk render, and also ports the changes from WorldPreview 3.0.0-5.0.0 for later versions, most ...
Generate a thread dump by using a program such as jVisualVM. Figure 2: A Thread Dump Using visualvm. The task on the left indicates the list of currently running processes. Click on the process for which you want the information, and select the thread tab to check the thread information...

Note the process ID number of the Java process (e.g. usingtop, agreponps -axw, etc.) and send aQUITsignal to the process with thekill -QUITorkill -3command1. For example: Raw kill -3 JAVA_PID Aside from the scripts suggested below or manually determining and providing the process id...
