    Description

      Due to a simple implementation bug, Epsilon GC did not extend the size of the issued TLABs to the max size configured by user, or set by default. This bug might have introduced performance penalties and was generally confusing during performance analysis. This is now fixed and backported to 13u and 11u. Users are advised to double-check their performance results before and after this update.
