There is a race when compiling build.tools.symbolgenerator.CreateSymbols: [2020-11-03T07:21:12,118Z] Error: LinkageError occurred while loading main class build.tools.symbolgenerator.CreateSymbols [2020-11-03T07:21:12,119Z] java.lang.ClassFormatError: Truncated class file [2020-11-03T07:21:12,125Z] Gendata.gmk:69: recipe for target '/.../build/macosx-x64-open/support/javadoc-symbols/symbols' failed [2020-11-03T07:21:12,125Z] make[3]: *** [/.../build/macosx-x64-open/support/javadoc-symbols/symbols] Error 1 [2020-11-03T07:21:12,127Z] make/Main.gmk:148: recipe for target 'jdk.javadoc-gendata' failed [2020-11-03T07:21:12,127Z] make[2]: *** [jdk.javadoc-gendata] Error 2 [2020-11-03T07:21:12,127Z] make[2]: *** Waiting for unfinished jobs....
This was caused by https://bugs.openjdk.java.net/browse/JDK-8216497, which started compiling the same buildtool twic, in different, independent makefiles, to the same output directory. The long term correct solution is to fix https://bugs.openjdk.java.net/browse/JDK-8241463. For now, I opted to just make sure the output is placed in separate directories to avoid the race. We will still compile the build tool twice; it's annoying but not a major performance problem. ------------- Commit messages: - 8255801: Race when building ct.sym build tools Changes: https://git.openjdk.java.net/jdk/pull/1037/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=1037&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8255801 Stats: 3 lines in 1 file changed: 0 ins; 0 del; 3 mod Patch: https://git.openjdk.java.net/jdk/pull/1037.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/1037/head:pull/1037 PR: https://git.openjdk.java.net/jdk/pull/1037
