Description

ARM JVM float ABI detection is failing in JNIFlags.cmake because JAVA_JVM_LIBRARY is not set at that point. The failure currently causes CMake to assume a soft-float JVM. This causes the build to fail with hard-float OpenJDK (but don't use that) and Oracle Java 8 Preview for ARM. Hopefully the April update of Oracle Java 7 will support hard-float as well.
