Hello Rory,

I ran the Ant testsuite on a Linux setup against this JDK 16 build 
16-ea+32-2190. No issues were noticed. The regression that was 
observed in the previous JDK 16 EA and was reported in 
https://bugs.openjdk.java.net/browse/JDK-8258246, is no longer present 
in this JDK 16 build.


As for the JDK 17 build 17-ea+5-266, the above reported regression 
continues to exist in that build (I guess because the JDK16 repo 
changes haven't yet been merged to JDK master repo or perhaps this JDK 
17 build is older). No other issues observed in this version.
