Scala 2.10 REPL javap doesn't support Java7 or Java8. It was fixed in Scala
2.11. See https://issues.scala-lang.org/browse/SI-4936

<br>
I am working with Spark 1.5.1 (official release), with Oracle Java8,<br>
on Ubuntu 14.04. echo $JAVA_HOME says &quot;/usr/lib/jvm/java-8-oracle&quot=
;.<br>
<br>
I&#39;d like to use :javap in spark-shell, but I get an error message:<br>
<br>
scala&gt; :javap java.lang.Object<br>
Failed: Could not load javap tool. Check that JAVA_HOME is correct.<br>
<br>
However ls $JAVA_HOME/lib/tools.jar shows that it is there.<br>
<br>
I tried starting spark-shell with -toolcp $JAVA_HOME/lib/tools.jar but<br>
I get the same error.<br>
<br>
For comparison, if execute scala and enter :javap java.lang.Object, it<br>
works as expected.<br>
<br>
Not sure where to go from here. Thanks for any advice.<br>
<br>
best,<br>
