Please review a fix for issue where it was seen that several nested classes rely on default constructors as part of their public API.
It's to be noted that "A no-arg public constructor is generated by the compiler for a class if it does not declare an explicit constructor. While convenient, this is inappropriate for many kinds of formal classes, both because the constructor will have no javadoc and because the constructor may be unintended." For the JDK, classes intended to be used outside of the JDK, public classes in exported packages, should not rely on default constructors. Proposed fix is to add explicit public no-arg constructors for public classes and protected no-arg constructor for public abstract classes for javax.swing module (as one part of overalll java.desktop change) CSR: https://bugs.openjdk.java.net/browse/JDK-8252908 ------------- Commit messages: - 8252721: Nested classes in Swing APIs rely on default constructors - 8252721: Nested classes in Swing APIs rely on default constructors - 8248532: Every time I change keyboard language at my MacBook, Java crashes Changes: https://git.openjdk.java.net/jdk/pull/72/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=72&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8252721 Stats: 252 lines in 42 files changed: 252 ins; 0 del; 0 mod Patch: https://git.openjdk.java.net/jdk/pull/72.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/72/head:pull/72 PR: https://git.openjdk.java.net/jdk/pull/72
