The ZIP_ReadEntry function in libzip.so used by the JVM to extract classes
from the system jar files allocates memory which is never freed. This
memory is allocated in 32KB blocks to hold the raw data to be inflated.

This only affects classes loaded from compressed entries in jar files in
the system classpath. Since rt.jar entries are not compressed, it is not
affected. However, i18n.jar is compressed and 32KB of malloc heap space is
leaked per class loaded.
