I see that JavaHL has a ClientContext class and the Java code creates a
private instance of this class. From what I can see in ClientContext.cpp it
stores the svn_client_ctx_t in the global pool.

    /* Create a long-lived client context object in the global pool. */
    SVN_JNI_ERR(svn_client_create_context(&persistentCtx,
JNIUtil::getPool()),
                );

I wonder if we could simply add a method to JavaHL to destroy this context?
 I do not see anywhere that the wc_context is created in JavaHL native code
so not sure if it would be possible to clear the pool used to store those.
