[lworld] RFR: 8327639: [lworld] test/jdk/java/lang/invoke/callerSensitive/CallerSensitiveAccess.java fails with --enable-preview

[Roger Riggs]

The test contains a bug in which it attempts to use streams from ModuleReader.list() after the ModuleReader has been closed.  Closing ModuleReader closes the underlying streams to the Jar/Zip file.

The bug is only exercised when a patched module is read. Currently, --enable-preview uses module patching of the java.base module to include a set of classes that have been converted to be value classes.

The test is modified to cache the results of the stream in a List and keep the scoped structure used by try-with-resources.
