- Clone and `gradle capsule` [any `photon` branch using the latest `capsule`](https://github.com/puniverse/photon/tree/capsule-osv) - Clone [`capsule-daemon`](https://github.com/puniverse/capsule-daemon) and uncomment [these two lines](https://github.com/puniverse/capsule-daemon/blob/master/src/main/java/DaemonCapsule.java#L134), then `gradle install` - Run the `photon` capsule wrapped in...

Deserializing fibers that used `stderr` results in `java.lang.ClassNotFoundException: org.gradle.util.LinePerThreadBufferingOutputStream$1` when running under Gradle

12

Gradle seems to replace `System.out.stderr` with [`LinePerThreadBufferingOutputStream` which inserts itself in a threadlocal](https://github.com/gradle/gradle/blob/77ea2907e4e1ce93667d8544c54961040b758422/subprojects/core/src/main/groovy/org/gradle/util/LinePerThreadBufferingOutputStream.java#L30) that triggers the issue upon deserialization. Workaround [f.e. here](http://stackoverflow.com/questions/5339499/resetting-standard-output-stream). Reproduce f.e. by inserting a `System.err` printout before...

Deserializing a fiber built from a JDK8 lambda results in `java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to co.paralleluniverse.fibers.FiberWriter`

JD8+. Reproduce by converting [this](https://github.com/puniverse/quasar/blob/v0.7.3/quasar-core/src/test/java/co/paralleluniverse/fibers/FiberTest.java#L790) to a lambda and then `gradle :quasar-core:jdk8Test`.

vertx-sync direct scheduling question

Hi guys, I came across a stacktrace where `vertx-sync` seems to start a fiber and then the very same thread executes it directly; I think this happens by default unless...
