JRuby 9.2.x is compatible with Ruby 2.5.x and stays in sync with C Ruby. As
always there is a mix of miscellaneous fixes so be sure to read the issue
list below. All users are encouraged to upgrade.
Ruby Standard Library
The Ruby Standard Library has been updated to Ruby 2.5.7. JRuby will
now report this as our equivalent compatible Ruby version. (#5917)
RubyGems has been updated to version 2.7.10.
Security Updates
This release removes an exploitable version of JQuery used by the rdoc
library. See
https://www.ruby-lang.org/en/news/2019/08/28/multiple-jquery-vulnerabilities-in-rdoc/
Java Modules Support
Java modules are better supported in this release by checking for
openness before attempting to reflect against classes from that module.
This should reduce the number of module warnings on Java 9+ and make it
easier to configure the JVM to open up appropriate modules and packages to
JRuby applications. See also the .jruby.java_opts file above, which can
help you manage module options. (#5841, 5832, #5843, #5855, #5860)
Java Launcher Improvements
JVM options can now be added to global or app-local .jruby.java_opts
files and automatically processed by the JRuby launcher. See JRuby Java
Options Files for more information. Note: This feature is not yet supported
by the JRuby native launcher, installed by default in RVM. We will release
an update to the native launcher soon. (#5824, #5826)
You can now pass --environment to the JRuby launcher to get a log of
exactly how we will execute your application. (#5840)
JRuby’s dev mode (via the --dev flag) adds additional options for Java
9+ and the OpenJ9 JVM. On OpenJ9, the -Xquickstart and -Xshareclasses flags
are passed via the OPENJ9_JAVA_OPTIONS environment variable. (#5831)
Memory Usage Reductions
Numerous changes in this release reduce the boot-time and run-time
memory use of JRuby applications. (#5837, #5832, #5874, #5880, #5885)
Thread-safety Improvements
Lock interruptibility broken in JRuby 9.2.8 has now been fixed. (#5863,
#5875
Process.wait APIs are now interruptible
Threads calling Process.wait, waitall, or waitpid will use the
pthread_kill native function to interrupt those operations. Previously
these threads were not interruptible. (#1050, #5848)
Native FFI improvements
When running JRuby via the “complete” jar file, we must unpack our
native FFI stub to an appropriate temporary location. If the default
location we use (the host system’s default “temp” location) is not readable
or does not allow executable code, we will present an informational error
indicating how to correct the issue. (#1302)
This release also includes native support for DragonFly BSD. (#5768,
#5828)
Time Zone Data
Time zone data has been updated to IANA 2019c. This update includes six
years of timezone changes. (#5951)
