All Implemented Interfaces:

Serializable

public class CRC32Exception
extends ZipException

Thrown to indicate a CRC-32 mismatch between the declared value in the Central File Header and the Data Descriptor or between the declared value and the computed value from the decompressed data. The prior case is detected on the call to BasicZipFile.getCheckedInputStream(java.lang.String), whereas the latter case is detected when the input stream returned by this method gets closed.

The exception's detail message is the name of the ZIP entry.
