July 14, 2021 - Android Release v1.8-1-ge12d821

A few minor changes to address issues on the Android ART runtime:

• A type conversion from a 64-bit integer to a 32-bit integer was resulting in a zero-length cache size. This was causing the engine to appear to be frozen and/or spew a lot of error message about cache-size.
• We were double-releasing a local reference, this was causing a lot of debug spew.
• Threads were attaching on the JNI side without a name value which was also causing a lot of debug spew.
