getLoadedBootJars

public Set<String> getLoadedBootJars()

Returns jars that this retransformer was asked to add to the boot classloader. Note that the returned set will not include those jars that were added to the instrumentor object at startup via the -javaagent command line argument.

Returns:

set of jar pathnames for all jars loaded in the boot classloader

getLoadedSystemJars

public Set<String> getLoadedSystemJars()

Returns jars that this retransformer was asked to add to the system classloader. Note that the returned set will not include those jars that were added to the instrumentor object at startup via the -javaagent command line argument.

Returns:

set of jar pathnames for all jars loaded in the system classloader
