Description Fabio Rossi 2020-04-03 08:45:16 UTC
When running the tool as normal user, I get the following exception:

$ java-ebuilder -c
Parsing portage tree @ /usr/portage ...
Exception in thread "main" java.lang.NullPointerException
	at org.gentoo.java.ebuilder.portage.PortageParser.parseCategory(PortageParser.java:236)
	at org.gentoo.java.ebuilder.portage.PortageParser.parseCategories(PortageParser.java:222)
	at org.gentoo.java.ebuilder.portage.PortageParser.parseTree(PortageParser.java:143)
	at org.gentoo.java.ebuilder.Main.refreshCache(Main.java:345)
	at org.gentoo.java.ebuilder.Main.main(Main.java:47)

This is due to the fact the array passed to the for loop is not empty list but a NULL pointer, on my system it happens when trying to inspect /usr/portage/packages which has the following mode bits: 

drwx------ 106 portage portage 4096  3 apr 10.08 /usr/portage/packages/

If the user is thought to be run as root the tool should check for the user id otherwise the array iteration should be fixed
