RELEASE NOTES

core-libs/java.lang

Issue Description
JDK-8297295

ThreadGroup.allowThreadSuspension is removed


The method java.lang.ThreadGroup.allowThreadSuspension(boolean) has been removed in this release. The method was used for low memory handling in JDK 1.1 but was never fully specified. It was deprecated and changed to "do nothing" in JDK 1.2 (1998).

security-libs/java.security

Issue Description
JDK-8286907

keytool -genseckey And -importpass Commands Warn if Weak PBE Algorithms Are Used


The keytool -genseckey and -importpass commands have been updated to warn users when weak password-based encryption algorithms are specified by the -keyalg option.

security-libs/javax.crypto

Issue Description
JDK-8288050

SunJCE provider now supports SHA-512/224 and SHA-512/256 as digests for the PBES2 algorithms


SunJCE provider is enhanced with additional PBES2 Cipher and Mac algorithms, e.g. those using SHA-512/224 and SHA-512/256 message digests. To be more specific, callers can now use SunJCE provider for "PBEWithHmacSHA512/224AndAES128", "PBEWithHmacSHA512/256AndAES128", "PBEWithHmacSHA512/224AndAES256", and "PBEWithHmacSHA512/256AndAES256" Cipher and "PBEWithHmacSHA512/224", and "PBEWithHmacSHA512/256" Mac.

core-libs/java.io

Issue Description
JDK-8208077

File::listRoots Changed To Return All Available Drives On Windows


The behavior of the method java.io.File.listRoots() on Microsoft Windows has changed in this release so that the returned array includes a File object for all available disk drives. This differs from JDK 10 to JDK 20, where this method filtered out disk drives that were not accessible or didn't have media present. This change avoids performance issues observed in these releases and also ensures that the method is consistent with the root directories in the iteration returned by FileSystem.getDefault().getRootDirectories().
