Precondition Violations (5)
Row |
Violation |
1 | Type org.jruby.runtime.builtin.IRubyObject of variable backtrace does not match with type org.jruby.compiler.impl.SkinnyMethodAdapter of variable clinitMethod |
2 | Expression initBacktrace() cannot be parameterized, because it has dependencies to/from statements that will be extracted |
3 | Expression beginClassInit() cannot be parameterized, because it has dependencies to/from statements that will be extracted |
4 | Expression initBacktrace() is a void method call, and thus it cannot be parameterized |
5 | Expression beginClassInit() is a void method call, and thus it cannot be parameterized |
