The jinfo command prints Java configuration information for a specified Java process or core file or a remote debug server. 

The configuration information includes Java system properties and Java Virtual Machine (JVM) command-line flags. 

If the specified process is running on a 64-bit JVM, then you might need to specify the -J-d64 option, 

for example: jinfo -J-d64 -sysprops pid.

This utility is unsupported and might not be available in future releases of the JDK. 

In Windows Systems where dbgeng.dll is not present, Debugging Tools For Windows must be installed to have these tools working. 

The PATH environment variable should contain the location of the jvm.dll 

that is used by the target process or the location from which the crash dump file was produced. 

For example, set PATH=%JDK_HOME%\jre\bin\client;%PATH% .
