Issue	Description
JDK-8229887	Using the ZIP File System (zipfs) Provider to Update a ZIP or JAR File Containing Uncompressed Entries Might Corrupt the File Using the ZIP File System (`zipfs`) to update a JAR or ZIP file might corrupt that file. Corruption occurs only if the JAR or ZIP file contains a non-compressed entry. If the JAR or ZIP file contains only compressed entries, as is typical, then no data corruption occurs. As a workaround, users can use the `jar` tool or the `java.util.zip` API to update JAR or ZIP files that contain non-compressed entries.

Issue	Description
JDK-8230646	Epsilon does not extend TLABs to max size 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.
