[bero <at> matterhorn tmp]$ wget http://bero.eu/java-source-list

[bero <at> matterhorn tmp]$ tr ' ' '\n' <java-source-list |sort |grep 
X509Certificate
libcore/luni/src/main/java/java/security/cert/X509Certificate.java
libcore/luni/src/main/java/javax/security/cert/X509Certificate.java

This is correct...

[bero <at> matterhorn tmp]$ tr ' ' '\n' <java-source-list |sort -u |grep 
X509Certificate
libcore/luni/src/main/java/javax/security/cert/X509Certificate.java

Note the missing .../java/java/security/cert/X509Certificate.java

[bero <at> matterhorn tmp]$ tr ' ' '\n' <java-source-list |sort |uniq |grep 
X509Certificate
libcore/luni/src/main/java/java/security/cert/X509Certificate.java
libcore/luni/src/main/java/javax/security/cert/X509Certificate.java

This is correct


The problem occurs (at least) with sort from coreutils 8.12, 8.13 and 
8.14.
