To:Debian Bug Tracking System From:Erich Schubert Subject:Bug#664515: Produces Classpath with extra ":" in front Date:Sun, 18 Mar 2012 15:41:16 +0100
 

Package: java-wrappers
Version: 0.1.24
Severity: normal

Weka 3.7.5 (but with the Debian launcher script, using java-wrappers) would not
start for me, with some NullPointerException after a long startup time. Looking
at the command run, it invokes this:

/usr/lib/jvm/java-6-openjdk-i386/bin/java -Xmx256m -classpath :/usr/share/java/weka.jar weka.gui.GUIChooser
Refreshing GOE props...
java.lang.NullPointerException
weka.gui.GUIChooser.<init>(GUIChooser.java:688)
weka.gui.GUIChooser.createSingleton(GUIChooser.java:254)
weka.gui.GUIChooser.main(GUIChooser.java:1507)

at weka.gui.GUIChooser.<init>(GUIChooser.java:688)
at weka.gui.GUIChooser.createSingleton(GUIChooser.java:254)
at weka.gui.GUIChooser.main(GUIChooser.java:1507)
null

Whereas, when I execute
/usr/lib/jvm/java-6-openjdk-i386/bin/java -Xmx256m -classpath /usr/share/java/weka.jar weka.gui.GUIChooser

weka would correctly start. The only difference is the extra ":" in the
classpath. Is there a particular reason why java-wrappers adds this, or can
it just be removed? Apparently this is interpreted as ".:" by some part of
weka, and it will cause a full scan of my home directory (apparently running
into a problem at some point, maybe with a dangling symlink or so).
