JAVA compatibility


Issue #1: Oracle Java 1.8 Affected software: LARA 3.1.5


Summary: Issue during migration: SSLHandshakeException - no available authentication scheme.
This error is received on a LARA 3.1.5 MigrationSource when launched over a LARA V3.2.1.11 DS. The LARA 3.1 installation runs on Java 1.8.0_231.

Description: This error is received on a LARA 3.1.5 MigrationSource when launched over a LARA V3.2.1.11 DS. The LARA 3.1 installation runs on Java 1.8.0_231.  After investigation, it seems that Java 1.8 update 191 changes it supported TLS encryption lists so that all DES TLS cipher suites were disabled and we think the SSL certificates for 3.1 were DES as this was the default algorithm at the time.

Prevention: The solution is to perform migration with a version < 1.8.191

Fix: This will be fixed with any future LARA V3.1 patches.

Issue #2: Java AdoptOpenjdk 11.0.8
 Affected software: LARA V3.2

Summary: Java 11.0.8 incompatibility.


Description: A change in Java 11.0.8 is incompatible with LARA V3.2. This should be rectified.

Prevention: To avoid this issue, a property (jdk.serialSetFilterAfterRead) can be set to true to revert the behaviour, but this would have to be manually set everywhere in the scripts launching LARA applications.

Fix: This will be fixed with any future LARA V3.2 patches.
