RELEASE NOTES, BY COMPONENT: core-libs/jdk.nashorn: JDK-8236933: JEP 372: Remove the Nashorn JavaScript Engine Summary ------- Remove the Nashorn JavaScript script engine and APIs, and the `jjs` tool. The engine, the APIs, and the tool were [deprecated for removal in Java 11](http://openjdk.java.net/jeps/335) with the express intent to remove them in a future release. Motivation ---------- The Nashorn JavaScript engine was first incorporated into JDK 8 via [JEP 174](http://openjdk.java.net/jeps/174) as a replacement for the Rhino scripting engine. When it was released, it was a complete implementation of the ECMAScript-262 5.1 standard. With the rapid pace at which ECMAScript language constructs, along with APIs, are adapted and modified, we have found Nashorn challenging to maintain. Non-Goals --------- This removal does not affect, in any way, the `javax.script` API. Description ----------- Two [JDK modules](http://openjdk.java.net/jeps/200#Design-principles) will be permanently removed: - `jdk.scripting.nashorn` -- contains the `jdk.nashorn.api.scripting` and `jdk.nashorn.api.tree` packages. - `jdk.scripting.nashorn.shell` -- contains the `jjs` tool. Risks and Assumptions --------------------- We assume that developers who rely on Nashorn have had enough notice of its proposed removal to make alternative arrangements. The deprecation-for-removal of Nashorn in JDK 11 was confirmed in June 2018, causing the proposed removal to be flagged at every use of the `jdk.nashorn.*` API and the `jjs` tool in JDK 11, 12, and 13. During this period, no set of credible developers expressed a clear desire to maintain Nashorn in JDK 14 and beyond. hotspot/runtime: JDK-8247371: Enable ShowCodeDetailsInExceptionMessages by default The default of the flag ShowCodeDetailsInExceptionMessages was changed to 'true'. The helpful NullPointerException messages of [JEP 358](http://openjdk.java.net/jeps/358) are now printed by default. The messages contain snippets of the code where the NullPointerException was raised. App deployers should double check the output of their web applications and similar usage scenarios. The NullPointerException message could be included in application error messages or be displayed by other means in the app. This could give remote attackers valuable hints about a potential vulnerable state of the software components being used. An example message is 'Cannot read field "c" because "a.b" is null'. The attacker knows that field b of a contains null which might be unintended and offer an opportunity for an attack. For more details of what the message can contain see the above mentioned [JEP 358](http://openjdk.java.net/jeps/358). security-libs/java.security: JDK-8250756: Added Entrust Root Certification Authority - G4 certificate The following root certificate has been added to the cacerts truststore: ``` + Entrust + entrustrootcag4 DN: CN=Entrust Root Certification Authority - G4, OU="(c) 2015 Entrust, Inc. - for authorized use only", OU=See www.entrust.net/legal-terms, O="Entrust, Inc.", C=US ``` JDK-8250860: Added 3 SSL Corporation Root CA Certificates The following root certificates have been added to the cacerts truststore: ``` + SSL Corporation + sslrootrsaca DN: CN=SSL.com Root Certification Authority RSA, O=SSL Corporation, L=Houston, ST=Texas, C=US + sslrootevrsaca DN: CN=SSL.com EV Root Certification Authority RSA R2, O=SSL Corporation, L=Houston, ST=Texas, C=US + sslrooteccca DN: CN=SSL.com Root Certification Authority ECC, O=SSL Corporation, L=Houston, ST=Texas, C=US ``` ALL FIXED ISSUES, BY COMPONENT: client-libs/2d: JDK-8244818: [macos] Java2D Queue Flusher crash while moving application window to external monitor client-libs/javax.accessibility: JDK-8249278: Revert JDK-8226253 which breaks the spec of AccessibleState.SHOWING for JList client-libs/javax.swing: JDK-8249251: [dark_mode ubuntu 20.04] The selected menu is not highlighted in GTKLookAndFeel core-libs: JDK-8248011: Improve javadoc of Foreign Memory Access API JDK-8247696: Incorrect tail computation for large segments in AbstractMemorySegmentImpl::mismatch JDK-8249205: Remove unnecessary trademark symbols core-libs/java.io: JDK-8247896: Invalid (@throw) tags in 2 java.io classes JDK-8249700: java/io/File/GetXSpace.java should be added to exclude list, and not @ignore-d core-libs/java.io:serialization: JDK-8248233: Avoid superfluous Class::isRecord invocations during deserialization JDK-8247532: Records deserialization is slow JDK-8247789: Remove use of reflection from test/jdk/java/io/Serializable/records/StreamRefTest.java core-libs/java.lang: JDK-8246098: API for Class::permittedSubclasses should clarify if returned elements are ordered or not JDK-8247899: HTML errors and warnings in threadPrimitiveDeprecation.html JDK-8247444: Trust final fields in records JDK-8217475: Unexpected StackOverflowError in "process reaper" thread JDK-8249217: Unexpected StackOverflowError in "process reaper" thread still happens core-libs/java.lang:class_loading: JDK-8247785: Small clarification of the javadoc about builtin class loaders core-libs/java.net: JDK-8248703: Clarify the behavior of java.net.NetworkInterface::equals JDK-8246114: java/net/MulticastSocket/Promiscuous.java fails after 8241072 (multi-homed systems) core-libs/java.nio: JDK-8249543: (bf) Force DirectBufferAllocTest to run with -ExplicitGCInvokesConcurrent JDK-8247880: bad HTML(href==...) in table JDK-8247959: doclint errors in NIO code JDK-8250770: Net.java translateToSocketException does not handle IOException core-libs/java.util: JDK-8249258: java/util/StringJoiner/StringJoinerTest.java failed due to OOM JDK-8242935: test/jdk/java/util/ServiceLoader/ReloadTest.java uses nashorn script engine core-libs/java.util.jar: JDK-8211974: move test/jdk/lib/testlibrary/java/util/jar/*.java to top-level library or a local library JDK-8249097: test/lib/jdk/test/lib/util/JarBuilder.java has a bad copyright core-libs/jdk.nashorn: JDK-8247956: remove scripts under bin/nashorn and doc/nashorn/source core-svc/debugger: JDK-8247784: Bad link causes invalid documentation JDK-8247958: minor HTML errors in com.sun.jdi core-svc/java.lang.management: JDK-8248061: bad reference in @throws in HotSpotDiagnosticMXBean core-svc/javax.management: JDK-8247894: Invalid @see in java.management globalization/locale-data: JDK-8250665: Wrong translation for the month of May in ar_JO, ar_LB and ar_SY globalization/translation: JDK-8249086: JDK 15 L10n resource file update - msg drop 10 hotspot/compiler: JDK-8248822: 8 vm/classfmt/atr_ann/atr_rtm_annot007/atr_rtm_annot00709 tests fail w/ AOT JDK-8252292: 8240795 may cause anti-dependence to be missed JDK-8247200: [aarch64] assert((unsigned)fpargs < 32) JDK-8246051: [aarch64] SIGBUS by unaligned Unsafe compare_and_swap JDK-8248597: [Graal] api/java_security/SignatureSpi/DelegationTests.html fails with Method "javasoft.sqe.tests.api.java.security.SignatureSpi.JCKSignatureSpi.clear" doesn't exist.
