[jruby-dev] [jira] (JRUBY-7010) RubyKernel.id_deprecated throws a Java::JavaNio::BufferOverflowException

[Diego Alonso (JIRA)]

Diego Alonso created JRUBY-7010 RubyKernel.id_deprecated throws a Java::JavaNio::BufferOverflowException Issue Type: Bug Affects Versions: JRuby 1.6.8 Assignee: Thomas E Enebo Created: 28/Nov/12 3:30 PM Description: A part of our code was calling the 'id' method in what we thought was a Rails ActiveRecord, but wasn't. That was calling the RubyKernel.id_deprecated method, which through RubyBasicObject logs a warning (warning: Object#id will be deprecated; use Object#object_id) The application runs well for some time, with that error being reported, but after a few days of heavy use, we get a BufferOverflowException. Please see stack trace below: java.nio.HeapByteBuffer.put(HeapByteBuffer.java:165) org.jruby.util.io.ChannelStream.bufferedWrite(ChannelStream.java:1058) org.jruby.util.io.ChannelStream.fwrite(ChannelStream.java:1237) org.jruby.RubyIO.fwrite(RubyIO.java:1480) org.jruby.RubyIO.write(RubyIO.java:1362) org.jruby.RubyIO$i$1$0$write.call(RubyIO$i$1$0$write.gen:65535) org.jruby.RubyClass.finvoke(RubyClass.java:715) org.jruby.javasupport.util.RuntimeHelpers.invoke(RuntimeHelpers.java:548) org.jruby.RubyBasicObject.callMethod(RubyBasicObject.java:361) org.jruby.common.RubyWarnings.warn(RubyWarnings.java:76) org.jruby.common.RubyWarnings.warn(RubyWarnings.java:81) org.jruby.RubyBasicObject.id_deprecated(RubyBasicObject.java:2130) org.jruby.RubyKernel.id_deprecated(RubyKernel.java:1915) org.jruby.RubyKernel$s$0$0$id_deprecated.call(RubyKernel$s$0$0$id_deprecated.gen:65535) org.jruby.runtime.callsite.CachingCallSite.cacheAndCall(CachingCallSite.java:292) org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:135) app.models.volume_aggregate.chained_5_rescue_1$RUBY$SYNTHETICrebuild_for_date(app/models/volume_aggregate.rb) So, yes, there was a bug in our system, which we have fixed, but it seems like something in JRuby is also failing. I have run some searches in jira, and it seems like there are several similar BufferOverflowException that have been fixed in different versions of JRuby, but it seems there is still something that is not totally right in 1.6.8.
