EVALUATION Using -Xverify:all doesn't make a difference.

EVALUATION VerifyOops didn't find a problem.
18-04-2011
EVALUATION The bug also happens on SPARC and x86 Linux, so it's not architecture or OS specific but a more fundamental bug: terminus:/export/twisti/jruby$ while [ $? -eq 0 ]; do bin/jruby.sh --server -Xcompile.invokedynamic=true -J-showversion -J-XX:+ShowMessageBoxOnError -J-XX:-PrintVMOptions -J-XX:+UseSerialGC test/test_thread.rb; done ... java version "1.7.0-ea-fastdebug" Java(TM) SE Runtime Environment (build 1.7.0-ea-fastdebug-b137) Java HotSpot(TM) Server VM (build 21.0-b08-internal-fastdebug, mixed mode) Loaded suite test/test_thread Started ............EXECUTION STOPPED: illegal bytecode sequence - method not verified ============================================================================== illegal bytecode sequence - method not verified ------------------------------------------------------------------------------ Execution stopped, print registers? ==============================================================================

EVALUATION Since it also happens with C1 and deoptimization disabled this is not a deopt problem (as I actually thought it is): intelsdv01:/export/twisti/jruby$ while [ $? -eq 0 ]; do bin/jruby.sh -J-XX:-DeoptC1 -Xcompile.invokedynamic=true -J-showversion -J-XX:+ShowMessageBoxOnError -J-XX:-PrintVMOptions -J-XX:+UseSerialGC test/test_thread.rb; done java version "1.7.0-ea-fastdebug" Java(TM) SE Runtime Environment (build 1.7.0-ea-fastdebug-b137) Java HotSpot(TM) Client VM (build 21.0-b08-internal-jvmg, mixed mode) Loaded suite test/test_thread Started ............============================================================================== illegal bytecode sequence - method not verified ------------------------------------------------------------------------------ Execution stopped, print registers? ==============================================================================

EVALUATION ScavengeRootsInCode=2 also triggers the bug.

EVALUATION It also reproduces on SPARC: terminus:/export/twisti/jruby$ while [ $? -eq 0 ]; do bin/jruby.sh --server -Xcompile.invokedynamic=true -J-showversion -J-XX:+ShowMessageBoxOnError -J-XX:-PrintVMOptions -J-XX:+UseSerialGC test/test_thread.rb; done java version "1.7.0-ea-fastdebug" Java(TM) SE Runtime Environment (build 1.7.0-ea-fastdebug-b137) Java HotSpot(TM) Server VM (build 21.0-b08-internal-fastdebug, mixed mode) Loaded suite test/test_thread Started ............EXECUTION STOPPED: illegal bytecode sequence - method not verified ============================================================================== illegal bytecode sequence - method not verified ------------------------------------------------------------------------------ Execution stopped, print registers? ==============================================================================
