RFR: 8273342: Null pointer dereference in classFileParser.cpp:2817

[Harold Seigel]

Hi,

Please review this fix to always return a non-null value from fieldDescriptor::generic_signature() when a generic signature exists, even in places in the function that should never get executed.  This will prevent code analyzers from complaining about possible null dereferences by callers of generic_signature().

The change was tested with Mach5 tiers 1-2 on Linux, Mac OS, and Windows, and Mach5 tiers 3-5 on Linux x64.

Thanks, Harold
