I recengly switched to java8, which caused some problems building archiva and
redback. I found some jira issues regarding build problems (issue [1] seems to
describe a JVM crash), so I decided to investigate the build state for openjdk
and oracle's jdk both for java7 and java8.
Here are the conclusions:
1. there is no difference between build success or failure between openjdk and
oracle jdk.
2. archiva-redback-core only builds on java7, and fails on java8 as follows:
- Redback :: Users Provider :: JDO with ERROR [JPOX.Enhancer] - Class
java.lang.String not found in classpath. :
org.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant
pool: 18.
- seems to be related with comment [2], though the issue [1] is about
jdk 1.7, which is confusing (also the reported build error is different)
- the error is reported at [3], and seems to be fixed in bcel 6.0,
which has not yet been released for some reason. Any idea how to work around
this in the meantime?
4. archiva has some non-deterministic test failures wich appear rarely on
java7, but at every build with java8. The error is in
org.apache.archiva.rest.services.BrowseServiceTest, due to a race between
server initialization and test running. I tried to fix it with [4]
I was unable to reproduce the exact failure described at [1] on any JDK, so I
am not sure if it still a problem for anyone. However, the BCEL poses a problem
for building redback with java8, so that might be worth investigating.
