Java verbose class loading

Question

I am trying to list the order in which the Java class loader is loading my classes. if I use -verbose parameter it will list every single interface/class it loa

Answer 1

Here's a sed expression that will parse the output of java -verbose:class to produce pairs of loaded class name and its jar file. You can further pipe through a sort to get unique jar files. For example,

java -verbose:class -version 2>/dev/null |
  sed -ne 's/\[Loaded \(.\+\) from \(.\+\)\]/\2/p' | 
  sort -u

outputs

/usr/local/jdk1.7.0_67/jre/lib/rt.jar
