On systems configured with the Transparent Huge Pages (THP) mode as ´madvise´, the option `-XX:+UseTransparentHugePages` does not enable huge pages when running with the default garbage collector G1.

A workaround to allow the use of transparent huge pages with G1 is to configure the THP mode as `always`:
```
# echo always > /sys/kernel/mm/transparent_hugepage/enabled
```

This issue will be fixed in a future update.
