Description

Using Java 1.7 with mlvm patchsets applied JRuby generates 'Trace/BPT trap' errors using rake, gem, or jirb commands. In addition a handful of the benchmark tests also generate this error.

I am using a build of mlvm from July 26 however I haven't tried using rake or gem with earlier versions of mlvm so this problem may or may not have been around before now.

$ jruby -S gem env

$ jirb

FYI: I put a tarball of the latest Mac OS X mlvm build I am using here (fastdebug enabled):

http://www.concord.org/~sbannasch/mlvm/java-1.7.0-internal-2010_07_26.tar.gz

java -version

openjdk version "1.7.0-internal-fastdebug"
OpenJDK Runtime Environment (build 1.7.0-internal-fastdebug-stephen_2010_07_26_09_07-b00)
OpenJDK Server VM (build 19.0-b03-fastdebug, mixed mode)

I also noticed that running these benchmarks in Java 1.7 (mlvm) also generated Trace/BPT Trap errors:

bench/bench_bind.rb
bench/bench_chmod.rb
bench/bench_erubis.rb
bench/bench_file_writing.rb
bench/bench_io_open.rb
bench/bench_io_read.rb

This is an issue in our native subsystem. The binary we ship with for darwin is not compatible with the Java 7 builds I've tried. Perhaps because it's a fat OS X library and the OpenJDK builds don't know how to cope with that?

With Apple "deprecating" their JDK, I think it's time we fixed this. Marking for 1.6.

FYI: still a problem

Testing with this version of MLVM:

http://www.concord.org/~sbannasch/mlvm/java-1.7.0-internal-mlvm-2010_09_25.tar.gz

Also with plain OpenJDK but I haven't created a tarball for that.

This is how I build OpenJDK now: http://gist.github.com/617451
And here's how I build the MLVM version: http://gist.github.com/243072
