* Do not use GetPrimitiveArrayCritical(...) due multiple not-fixed bugs related to GCLocker Motivation: GetPrimitiveArrayCritical(...) may cause multiple not-fixed bugs related to the GCLocker while there is little gain for our use-case. We should just use GetByteArrayRegion(...) and copy into a small on-stack buffer.

Modifications: Replace GetPrimitiveArrayCritical(...) with GetByteArrayRegion(...) Result: Less risks hitting GCLocker related bugs. |
