All Implemented Interfaces:

Test

public class DefiniteLengthAllocationTest

extends SimpleTest

Regression coverage for the definite-length materialization allocation guard in . When wraps a raw (non-array, non-file) stream, the per-object limit falls back to (), so allocating the full declared length up front let a short crafted header - an OCTET STRING declaring a near-heap length with no body - drive an OutOfMemoryError before any data was read (CWE-789). The buffer is now grown as bytes actually arrive: a short input allocates only a bounded working buffer, a well-formed object still materializes correctly, and a truncated object still fails with the established "DEF length [] object truncated by []" EOFException.
