"jimage info|list" - Listing JIMAGE Entries

This section provides a tutorial example on how to use 'jimage info|list' commands to view JIMAGE file info and list IMAGE entries.

The first command to learn is the "jimage info" command, which prints a high level summary of the given JIMAGE file.

Here is what I did to run the "jimage info" command on the JIMAGE file of the default JRE of my JDK 10 installation:

herong> jimage info \progra~1\java\jdk-10.0.1\lib\modules

 Major Version:  1
 Minor Version:  0
 Flags:          0
 Resource Count: 51195
 Table Length:   51195
 Offsets Size:   204780
 Redirects Size: 204780
 Locations Size: 1073419
 Strings Size:   1122343
 Index Size:     2605350

The second command to learn is the "jimage list" command, which lists all entries in the given IMAGE file:

herong> jimage list --verbose \progra~1\java\jdk-10.0.1\lib\modules | more

jimage: \progra~1\java\jdk-10.0.1\lib\modules
