Bug#751126: japi-compliance-checker: Incompatibility with Java 8 (internal error - can't read method signature)

[Emmanuel Bourg <ebourg@apache.org>]

Source: japi-compliance-checker
Version: 1.3.6-1
Severity: important
User: debian-java@lists.debian.org
Usertags: openjdk-8-transition

japi-compliance-checker doesn't work when OpenJDK 8 is used by default:

  ebourg@icare:~$ japi-compliance-checker -test
  
  verifying detectable Java library changes
  reading classes 1.0 ...
  ERROR: internal error - can't read method signature
  ERROR: test result: FAILED (0 breaks found)


Switching to Java 7 solves this issue:

  ebourg@icare:~$ sudo update-java-alternatives --set java-1.7.0-openjdk-amd64
  update-alternatives: error: no alternatives for iceweasel-javaplugin.so
  update-java-alternatives: plugin alternative does not exist: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
