The default value of 8MB has since proven to be too low for some JARs in general use. This change doubles it to 16MB, while still being much lower than the previous `MAX_ARRAY_SIZE` value of `Integer.MAX_VALUE - 8`

@gnu-andrew I think we should do this in jdk11u to make it part of the October update (as it is for OpenJDK 17 and 21). If you agree, please transplant the PR to jdk11u.
