that's because PHP's Exception::getMessage() shadows java.lang.Throwable.getMessage(). 

Please either use getLocalizedMessage() or access "message" directly (which invokes the Java Bean getter "getMessage") or pass the Java message to PHP's exception constructor.

That's why the bridge did not provide a resonable default for it. 

However, if you extend from Exception, you can access the $message property directly. The following code creates a new Exception and fills PHP's exception property with the exception obtained from Java:

<?php

require_once("java/Java.inc");
class my_JavaException extends java_InternalException {
  function __construct ($proxy, $message) { 
    $this->message = $message;
    parent::__construct($proxy->__delegate);
  }

}
class my_ThrowExceptionProxyFactory extends java_ThrowExceptionProxyFactory {
  function checkResult($result) {
	throw new my_JavaException ($result, $result->getCause()->message);
  }
}
$client = __javaproxy_Client_getClient();
$client->throwExceptionProxyFactory = 
         new my_ThrowExceptionProxyFactory($client);

// test
java_autoload("/home/jost/Test.jar");
try {
$test = new Test(true);
} catch (Exception $e) {
  echo $e->getMessage();
}
