thanks

Grave because this causes odd errors in various Java compilation tasks,and possibly in some Java applications, to make sure this versiondoesn't easily enter testing.

Apparently this upload causes various build problems in particular withMaven (surefire) but also ant.

Here is an ant error when trying to "ant compile" UMLgraph:https://github.com/dspinellis/UMLGraph

---

compile:

[javac] Compiling 20 source files to/home/erich/workspace/UMLGraph/build [javac]/home/erich/workspace/UMLGraph/src/main/java/org/umlgraph/doclet/ClassGraph.java:323:error: cannot access ClassDoc [javac] optionProvider.getOptionsFor(c instanceof ClassDoc? (ClassDoc) c : c.containingClass()) //

    [javac]                       ^
    [javac]   class file for ClassDoc not found

---

Now tools.jar is on the classpath, it seems to be in the package (butpossibly the binary is broken?)


With maven, I get a different failure:

---

[INFO] --- maven-surefire-plugin:2.12.4:test (default-test) @ umlgraph ---

[INFO] Surefire report directory:/home/erich/workspace/UMLGraph/target/surefire-reports

VM crash orSystem.exit called ? -> [Help 1]

The same surefire problem was also reported here:https://stackoverflow.com/questions/53010200/maven-surefire-could-not-find-forkedbooter-class/53016532#53016532


On other systems, the package builds fine, including on Travis CI.

It seems this only affects certain (system?) class loader scenarios -surefire adds a jar, and the ant build needs the tools.jar.

My guess is that the backport of the security fixes didn't completelywork...
