Javassist with Maven

[pcman312]

I'm trying to do some byte code manipulation with Javassist using Maven. I keep getting a compilation error:

[pathToTheFile]:[59,18] cannot access com.sun.jdi.connect.IllegalConnectorArgumentsException
class file for com.sun.jdi.connect.IllegalConnectorArgumentsException not found
		HotSwapper hs = new HotSwapper(debugPort);

It's as if the JDK is missing a class file. I have the sun JDK installed and I know that maven is using it because when I do a mvn -v call it gives me this (I'm using Ubuntu by the way):

Apache Maven 2.2.1 (rdebian-1)
Java version: 1.6.0_22
Java home: /usr/lib/jvm/java-6-sun-1.6.0.22/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux" version: "2.6.31-22-generic" arch: "amd64" Family: "unix"

I have this as my pom file (this is currently just a test project to make sure that I can get everything set up correctly):

Any ideas on how to fix this problem?

Turns out it wasn't loading the tools.jar library in the jdk lib folder. I added this to the pom file and it worked:

<dependency>
	<groupId>sun.jdk</groupId>
	<artifactId>tools</artifactId>
	<version>1.5.0</version>
	<scope>system</scope>
	<systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>

I should note that this solution apparently doesn't work on mac's. We've replaced the dependency with a profile instead:

<profiles>
	<profile>
		<id>default-tools.jar</id>
		<activation>
			<property>
				<name>java.vendor</name>
				<value>Sun Microsystems Inc.</value>
			</property>
		</activation>
		<dependencies>
			<dependency>
				<groupId>com.sun</groupId>
				<artifactId>tools</artifactId>
				<version>1.5.0</version>
				<scope>system</scope>
				<systemPath>${java.home}/../lib/tools.jar</systemPath>
			</dependency>
		</dependencies>
	</profile>
</profiles>
