Bryan Pendleton commented on DERBY-6998: ---------------------------------------- > thought that Java 11 came before Java 1.2. Back to the future! Slightly more seriously: we still have code in the Derby codebase that changes its behavior relevant to JDK 1.2??!!! That was, what, 1995? Actually, Wikipedia says 1998: https://en.wikipedia.org/wiki/Java_version_history At any rate, that's 20 years ago! > Make it possible to build Derby cleanly using JDK 10 > ---------------------------------------------------- > > Key: DERBY-6998 > URL: https://issues.apache.org/jira/browse/DERBY-6998 > Project: Derby > Issue Type: Bug > Components: Build tools > Affects Versions: 10.15.0.0 > Reporter: Rick Hillegas > Priority: Major > Attachments: derby-6998-01-ab-tightenReturnType.diff, > derby-6998-02-aa-supportForJDK11.diff, > derby-6998-03-aa-reenableEncryptionTestsOnJDK11.diff, > derby-6998-04-aa-increaseCertificateLifetime.diff, sslHandshake.tar > > > When I build Derby using JDK 10, I get the following warning: > {noformat} > [javac] > /Users/rhillegas/derby/mainline/trunk/java/engine/org/apache/derby/iapi/types/SqlXmlUtil.java:728: > warning: [unchecked] getPrefixes(String) in NullNamespaceContext implements > getPrefixes(String) in NamespaceContext > [javac] public Iterator getPrefixes(String namespaceURI) { > [javac] ^ > [javac] return type requires unchecked conversion from Iterator to > Iterator<String> > [javac] 1 warning > {noformat} > I will clean this up. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
