Error on replacing the database file

[thranduil]

We use Ip2proxy where we load database using IP2Proxy.IOModes.IP2PROXY_MEMORY_MAPPED mode.
When a background process replaces database file (using cp command) we receive one of the following errors when calling GetProxyType() method.

See stacktrace:

java.lang.InternalError: a fault occurred in a recent unsafe memory access operation in compiled Java code
	at com.ip2proxy.IP2Proxy.Read128(IP2Proxy.java:1210)
	at com.ip2proxy.IP2Proxy.Read32Or128(IP2Proxy.java:1202)
	at com.ip2proxy.IP2Proxy.ProxyQuery(IP2Proxy.java:800)
	at com.ip2proxy.IP2Proxy.GetProxyType(IP2Proxy.java:256)

and

java.lang.IllegalArgumentException: newPosition < 0: (-1157713828 < 0)
	at java.base/java.nio.Buffer.createPositionException(Buffer.java:341)
	at java.base/java.nio.Buffer.position(Buffer.java:316)

	at com.ip2proxy.IP2Proxy.ProxyQuery(IP2Proxy.java:837)
	at com.ip2proxy.IP2Proxy.GetProxyType(IP2Proxy.java:256)

We are running openjdk version "17.0.8.1" 2023-08-24 and Ubuntu 22.04.3 LTS.

Any help would be welcome.

I think you should close and reopen IP2Proxy instance when replacing the file

Yes, that should be the correct way to replace the BIN file.
