[HARMONY-2130] [drlvm][kernel] DaCapo antlr fails on drlvm

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Component/s: DRLVM

Description

The DaCapo antlr benchmark appears to use a version of antlr supplied by drlvm/harmony class libraries. The dacapo benchmark is based on antlr v2.7.2, and running

$ $DRLVM_HOME/jre/bin/java -jar $HOME/dacapo-2006-10.jar antlr
===== DaCapo antlr starting =====
Running antlr on grammar antlr/cpp/calc.g
ANTLR Parser Generator Version 2.7.5 (20050128) 1989-2005 jGuru.com

whereas on J9, we get
$ /opt/ibm-java2-i386-50/bin/java -jar $HOME/dacapo-2006-10.jar antlr
===== DaCapo antlr starting =====
Running antlr on grammar antlr/cpp/calc.g
ANTLR Parser Generator Version 2.7.2 1989-2003 jGuru.com

A workaround is possible by setting

-Xbootclasspath/p:antlr.jar

but this is clearly undesirable.
