protected final ILibraryResolver	_resolver
static final String[]	KNOWNLIBPATHS_DEFAULT_32
static final String[]	KNOWNLIBPATHS_DEFAULT_64
static final String	KNOWNLIBPATHS_PROPERTY	Setting this system property will cause the dump reader to retry searches for Linux libraries without fully qualified names by prepending the specified paths in turn.
static final String	USELOADEDLIBRARIES	Setting this system property (to anything) will cause the dump reader to only search for libraries that are present in the core file because the process loaded them and not to use any that are separately on disk *OR* attached to the end of the core file by the diagnostics collector.
