ArrayIndexOutOfBoundsException when using TracePoint

[aryeh-looker]

Unfortunately no simple, reproducible case at the moment (the application this occurs in is large and complex) and on an older version of JRuby.

Environment

Provide at least:

• jruby 9.1.17.0 (2.3.3) 2018-04-20 d8b1ff9 Java HotSpot(TM) 64-Bit Server VM 25.221-b11 on 1.8.0_221-b11 +jit [darwin-x86_64]
• using --debug flag for TracePoint support
• Darwin MacBook-Pro.local 18.7.0 Darwin Kernel Version 18.7.0: Tue Aug 20 16:57:14 PDT 2019; root:xnu-4903.271.2~2/RELEASE_X86_64 x86_64

Expected Behavior

Without using TracePoint, no ArrayIndexOutOfBoundsException exceptions are thrown.

Actual Behavior

Exceptions when using TracePoint.new(:line)

could you please try 9.2.8.0 ... if the issue reproduces.
since 9.1 likely won't get any fixes.
