toJava coersion regression when binding to JNDI

[kares]

... can't seem to wrap my head around it - for now :

# jruby -Ijdbc-derby/lib -J-cp tomcat-catalina.jar:tomcat-juli.jar 9000_regression.rb

java.lang.System.set_property(
    javax.naming.Context::INITIAL_CONTEXT_FACTORY,
    'org.apache.naming.java.javaURLContextFactory'
)
java.lang.System.set_property(
    javax.naming.Context::URL_PKG_PREFIXES,
    'org.apache.naming'
)

puts init_context = Java::JavaxNaming::InitialContext.new
begin
  init_context.create_subcontext 'jdbc'
rescue javax.naming.NameAlreadyBoundException
end

require 'jdbc/derby'
Jdbc::Derby.load_driver

data_source = org.apache.derby.jdbc.EmbeddedDataSource.new
data_source.database_name = "memory:DerbyDB-JNDI"
data_source.create_database = "create"
data_source.user = "sa"
data_source.password = ""

Java::JavaxNaming::InitialContext.new.bind 'jdbc/DerbyDB', data_source

bound = Java::JavaxNaming::InitialContext.new.lookup 'jdbc/DerbyDB'
puts bound
puts bound.java_class

for some reason under 9K this is no longer bound as a javax.sql.DataSource but instead as a javax.naming.Reference - EmbeddedDataSource implements both ... must be some spooky toJava conversion going around

several .jars are needed to run the script

• gem install jdbc-derby thus require 'jdbc/derby' will work
• download http://repo2.maven.org/maven2/org/apache/tomcat/tomcat-juli/7.0.61/tomcat-juli-7.0.61.jar
• download http://repo2.maven.org/maven2/org/apache/tomcat/tomcat-catalina/7.0.61/tomcat-catalina-7.0.61.jar

add'em to class-path e.g. jruby -J-cp tomcat-catalina-7.0.61.jar:tomcat-juli-7.0.61.jar 9000_regression.rb

@mkristian do you recall if you did actually something about this one ... or now the cause ?

verified - working fine in 9.0.5
