Serial port reading - Error : EXCEPTION_ACCESS_VIOLATION - C [rxtxSerial.dll+0x5b00]

2

Currently I'm trying to read serial port. Working fine in Linux. But facing error in Windows machine.

I followed this link to read serial port and Downloaded RXTX library from here for windows machine (JAR + DLL file).

OS : Windows 10 with 64bit

Java jre : Jre 1.8.0_261 VERSION.

Exception throws when read through input stream.

Error log :

TL;DR: Do not use 1.8.0_261 use 1.8.0_251 instead

I tried to reproduce this error with 1.8.0_181, 1.8.0_251 and 1.8.0_261 using Windows 10.0 , 64 bit Build 18362 (10.0.18362.1082).

I could only reproduce this error with Jre 1.8.0_261. u181 and u251 worked fine for me. I would suggest to use java 8 u251 from https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html .
