AprPool::getAprPool() returns NULL, causing access violation and application crash

                 Key: AMQCPP-388
             Project: ActiveMQ C++ Client
          Issue Type: Bug
          Components: Decaf
    Affects Versions: 3.2.3
         Environment: Windows xp service pack 3, ActiveMQ broker 5.3.1, apr 1.4.2, apr-util
1.3.9, apr iconv 1.2.1

            Reporter: Helen Huang
            Assignee: Timothy Bish
             Fix For: 3.2.3

Our application that uses activemq c++ client lib crashed with the following dump:

Thread 87 - System ID 3780

Function     Arg 1     Arg 2     Arg 3   Source

LIBAPR_1!APR_PVSPRINTF+8In scotapp.dmp the assembly instruction at libapr_1!apr_pvsprintf+8
in C:\scot\dll\libapr-1.dll has caused an access violation exception (0xC0000005) when trying
to read from memory location 0x0000002c on thread 87

On the call stack, we saw that following function from class decaf::lang::Exception was called:
void Exception::buildMessage( const char* format, va_list& vargs ) {

    // Allocate buffer with a guess of it's size
    AprPool pool;

    // Allocate a buffer of the specified size.
    char* buffer = apr_pvsprintf( pool.getAprPool(), format, vargs );

    // Guessed size was enough. Assign the string.
    message.assign( buffer, strlen( buffer ) );

The first parameter passed into apr_pvsprintf was NULL, causing the crash. Could you please
take a look and see if there is any bug in the activemqcpp code that could cause the problem.
