How to install Oracle Java 13 on Ubuntu 18.04, 16.04, 19.04, 19.10

Oracle will provide Java 13 as the Oracle OpenJDK release using the open source GNU General Public License v2, with the Classpath Exception (GPLv2+CPE), and also under a commercial license for those using the Oracle JDK release as part of an Oracle product or service, or who do not wish to use open source software.

Java 13 Changelog

Five enhancements are delivered with Java 13, inclusive of two preview features:

JEP 350 – Dynamic CDS Archives: Extends application class-data sharing to allow the dynamic archiving of classes at the end of Java application execution. The archived classes will include all loaded application classes and library classes that are not present in the default, base-layer CDS archive.

JEP 351 – ZGC: Uncommit Unused Memory: Enhances the z garbage collector to return unused heap memory to the operating system.

JEP 353 – Reimplement the Legacy Socket API:  Replaces the underlying implementation used by the java.net.Socket and java.net.ServerSocket APIs with a simpler and more modern implementation that is easy to maintain and debug. The new implementation will be easy to adapt to work with user-mode threads, a.k.a. fibers, currently being explored in Project Loom.

JEP 354 – Switch Expressions (Preview): Extends switch so it can be used as either a statement or an expression, which will simplify everyday coding, and prepare the way for the use of pattern matching (JEP 305) in switch.

How to install Oracle Java 11 long-term support on Ubuntu

   Java 11 has arrived. The new release is the first planned appearance of Oracle's long-term support (LTS) releases, although Oracle has also grandfathered in Java 8 as an LTS release to help bridge the gap between the old release model and the new approach

Java 11 Changelog

• Standardize the incubated HTTP Client API introduced in JDK 9, via JEP 110, and updated in JDK 10
• New Collection.toArray(IntFunction) Default Method
• The locale data based on the Unicode Consortium's CLDR (Common Locale Data Registry) has been updated for JDK 11.
• Lazy Allocation of Compiler Threads
• ZGC (Experimental): a brand-new garbage collector designed for sub-10ms pause times (even on large heaps) with an aim of no more than a 15% performance penalty.
• Epsilon GC is the new experimental no-op garbage collector. Epsilon GC only handles memory allocation, and does not implement any memory reclamation mechanism. It is useful for performance testing, to contrast costs/benefits of other GCs.

How to Install GScan2PDF 2.2.0 release on Ubuntu 18.04

    gscan2pdf is a GUI to ease the process of producing PDFs or DjVus from scanned documents. You scan one or several pages in with File/Scan, and create a PDF of selected pages with File/Save PDF. At maturity, the GUI will have similar features to that of the Windows Imaging program, but with the express objective of writing a PDF, including metadata. Scanning is handled with SANE via scanimage. PDF conversion is done by libtiff. Perl is used for portability and ease of programming, with gtk2-perl for the GUI. This should therefore work more or less out of the box on any system with gtk2-perl, scanimage, and libtiff.

GScan2PDF 2.2.0 Changelog: 

• Check validity of device blacklist regex when applying preferences
• Modify preference “Force new scan job between pages” to only take effect when scanning from flatbed.
• Fixed crash switching frontend option in Edit/Preferences between libimage-sane-perl and scanimage.
• Fixed visibility of scan widgets when switching from libimage-sane-perl to scanimage.
• Collect all warning and error messages in one dialog.
