Fix issue with call sites on constructors without DUP bytecode #9698

manuel-alvarez-alvarez · 2025-10-08T12:26:45Z

What Does This Do

Ignores constructor call sites when there is no corresponding DUP instruction following a NEW. This can occur when the created instance is immediately discarded and never used in the code.

Motivation

We've received an escalation related to a verification error:

Attempt to pop empty stack.
Current Frame:
bci: @24
flags: { }
locals: { 'java/lang/String', 'java/lang/String' }
stack: { uninitialized 10, '[Ljava/lang/Object;' }

The issue is caused by stack manipulation operations performed by IAST when applying call site advices. In the case of constructors, the instrumentation expects a DUP instruction to follow the NEW operation. However, in this particular instance, the bytecode sequence was:

new java/net/URI
aload 1
invokespecial java/net/URI.<init>(Ljava/lang/String;)V

Since the created instance is immediately discarded by the Java code, we can safely ignore these call sites.

Additional Notes

As a future improvement, we could revisit this logic and explore applying call site advices to this case as well.
