Hi,
please review this patch to remove the set of concealed packages from
ModuleDescriptor and instead only calculate it on demand.
Webrev: http://cr.openjdk.java.net/~redestad/8159334/webrev.01/
Bug: https://bugs.openjdk.java.net/browse/JDK-8159334
The conceals() method is currently used primarily by tools (jmod,
jlink), but never during startup or normal execution. Removing creation
of it drops around 35Kb of heap data from a hello world program (on a
JDK image) as well as giving a small improvement to startup time by
virtue of creating fewer sets during bootstrap.
Thanks!
