hugegraph, hugegraph-toolchain, hugegraph-commons consider use Java 11, also compatible with Java 8 now.
hugegraph-computer required to use Java 11, not compatible with Java 8 now!

v1.2.0 may be the last major version compatible with Java 8, compatibility with Java 8 will totally end in v1.5 when PD/Store merged into master branch (Except for the java-client).

HugeGraph 1.3.0 Release Notes

Mon, 01 Jan 0001 00:00:00 +0000

Operating Environment / Version Description

consider using Java 11 in hugegraph/toolchain/commons, also compatible with Java 8 now.
hugegraph-computer required to use Java 11, not compatible with Java 8!
Using Java8 may loss some security ensured, we recommend using Java 11 in production env with AuthSystem enabled.

1.3.0 is the last major version compatible with Java 8, compatibility with Java 8 will end in next release(1.5.0) when PD/Store merged into master branch (Except for the java-client).
