Code Review Request, JDK-8207029 Unable to use custom SSLEngine with default TrustManagerFactory after updating to JDK 11 b21

The code itself looks good, but I didn't see a regression tests.  Is 
this what JDK-8207174 will be for?

If I understand your question correctly, custom KM/TM are quite common. 
I routinely write custom impls to wrap functionality around the behavior 
of the stock TM/KM.  e.g. outputting debug information.

class MyTM extends X509TrustManager {
     private final X509TrustManager tm;
     MyTM(X509TrustManager tm) {
         theTM = tm;
