Java::JavaLang::NoClassDefFoundError (java/sql/Date) #6608
Description
Environment Information
Provide at least:
- JRuby version: 9.2.13.0 & 9.2.16.0
Picked up JAVA_TOOL_OPTIONS: -Djava.library.path=/nix/store/9l06v7fc38c1x3r2iydl15ksgz0ysb82-glibc-2.32/lib
jruby 9.2.13.0 (2.5.7) 2020-08-03 9a89c94bcc OpenJDK 64-Bit Server VM 11.0.9+0-adhoc..source on 11.0.9+0-adhoc..source +jit [linux-x86_64]
- Operating system and platform:
Linux fmzakari-glaptop 5.7.17-1rodete5-amd64 #1 SMP Debian 5.7.17-1rodete5 (2021-01-08) x86_64 GNU/Linux
Expected Behavior
Attempting to call to_java on a RubyTime object and have it return a java.sql.Date object returns NoClassDefFoundError.
What is perculiar is that I can clearly create a java.sql.Date, so it seems to be accessible via my classpath.
Here is a minimal reproduction with irb:
# let us prove first that java.sql.Date works!
irb(main):013:0> date = java.sql.Date.new(0)
=> #<Java::JavaSql::Date:0x2715644a>
# now fetch the class
irb(main):014:0> clazz = java.sql.Date.java_class
=> class java.sql.Date
# lets create a RubyTime object now
irb(main):015:0> t = Time.new(0)
=> 0000-01-01 00:00:00 -0752
# lets try to cast it to java.sql.Date
irb(main):016:0> t.to_java(clazz)

Java::JavaLang::NoClassDefFoundError (java/sql/Date)
A bit of a headscratcher for me since right before the call to to_java, you can see it working.
Actual Behavior
I expect the cast to work.
If I change the JDK we are using to JDK8, I see that the results work as intended.
irb(main):001:0> clazz = java.sql.Date.java_class
=> class java.sql.Date
irb(main):002:0> t = Time.new(0)
=> 0000-01-01 00:00:00 -0752
irb(main):003:0> t.to_java(clazz)
=> #<Java::JavaSql::Date:0x5223e5ee>
There is something funky here going on with module-loading.
