If I do something that results in an error, e.g. using Java 7u45 and running

> tool-wrapper.bat foo

it fails with 

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tomcat/util/ExceptionUtils

The cause is that org.apache.catalina.startup.Tool depends on ExceptionUtils class that is not present in bootstrap.jar.

When I do something successfully, e.g. run

> digest.bat -a md5 helloworld

it completes successfully.


Alternatively, we can add lib/tomcat-util.jar to the classpath created by tool-wrapper{.bat|.sh} script, or add the ExceptionUtils class to bootstrap.jar.

Tool class also depends on org.apache.catalina.Globals, but that only pulls in several constant strings and does not cause problems at runtime.
