Hello;

I've written a Java program which uses Postgresql via JDBC. The program works fine on all RedHat systems I've tested except one, where it yields an UnsatisifiedLinkError. Here is the stack trace:

sun.misc.VM.latestUserDefinedLoader0(Native
Method)
sun.misc.VM.latestUserDefinedLoader(VM.java:411)
java.io.ObjectInputStream.latestUserDefinedLoader(ObjectInputStream.java:2351)
java.io.ObjectInputStream.resolveClass(ObjectInputStream.java:686)
java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1866)
java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1749)
java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2040)
java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1571)
java.io.ObjectInputStream.readObject(ObjectInputStream.java:431)
org.postgresql.ds.common.BaseDataSource.readBaseObject(BaseDataSource.java:1210)
org.postgresql.ds.common.BaseDataSource.initializeFrom(BaseDataSource.java:1220)
org.postgresql.ds.PGPoolingDataSource.initialize(PGPoolingDataSource.java:267)
org.postgresql.ds.PGPoolingDataSource.getConnection(PGPoolingDataSource.java:324)

Any ideas?

Thanks in advance.

What is different about the system that throws the error?

For example:

OS version
JDBC version
Postgres version
Java version

Thanks in advance.

Thank you for your reply.

OS on working system: Linux 3.10.0-693.11.6.el7.x86_64 x86_64
OS on problem system: Linux 3.10.0-693.21.1.el7.x86_64 x86_64

JDBC version on both systems: 9.4.1209

Postgres version on both systems: 9.6.5 on x86_64-redhat-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-11), 64-bit

Java version on both systems:

openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-b10)
OpenJDK 64-Bit Server VM (build 25.171-b10, mixed mode)

Hmm.
So what was the UnsatisifiedLinkError message, before the traceback above?

Should OpenJDK be looking for a sun class?

Ah ha, that's it. Part of the deployment on the problem system was outdated.

Thanks to all.
