Looks like its vthread preview feature related

Also from that jdk_net target see:

Will presume since they are not implemented these need to be excluded for AIX.

[smlambert]

The action to take here is to exclude the java/net/vthread/HttpALot.java test case on AIX (and other platforms where it is not supported).

This can be done by adding lines into the ProblemList file, at the end of the jdk_net section:
https://github.com/adoptium/aqa-tests/blob/master/openjdk/excludes/ProblemList_openjdk19.txt#L206

hi @smlambert i would want to take on this one

[smlambert]

Looking at the live test runs, there are 2 more testcases that should get excluded as part of this issue:

@smlambert i am going to take on this as well
