Specify classloader

The classloader that loads the class can be found through the sc{{}} command.

sc -d org.springframework.context.ApplicationContext{{exec}}

After obtaining the hashcode of org.springframework.boot.loader.LaunchedURLClassLoader using the above command, you can use the -c or --classloader parameter to specify it. Here, we use --classLoaderClass to specify the classloader:

vmtool --action getInstances --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader --className org.springframework.context.ApplicationContext{{execute T2}}
