java - Can jmethodID initialized on one thread be used in another thread? -

-

can use jmethodid intialized on 1 thread in thread ? asked because jvm crashing when run jni program,in have initialized jmethodid on 1 thread , using in thread. thinking if reason.

i have kept jmethodid global varibale declaring @ top. in 1 of call initialize , in subsequent calls attempt reuse it.

quoting jni specification:

a field or method id not prevent vm unloading class id has been derived. after class unloaded, method or field id becomes invalid. native code, therefore, must make sure to:

keep live reference underlying class, or  recompute method or field id

if intends use method or field id extended period of time.
