java - Typesafe config - Null Pointer Exception -


i manually constructing classpath play/scala/akka application can use scalatest runner test application during different stages of ci pipeline without need recompile. however, following error:

java.lang.nullpointerexception:   @ com.typesafe.config.impl.parseable$parseableresources.rawparsevalue(parseable.java:509)   @ com.typesafe.config.impl.parseable$parseableresources.rawparsevalue(parseable.java:492)   @ com.typesafe.config.impl.parseable.parsevalue(parseable.java:171)   @ com.typesafe.config.impl.parseable.parsevalue(parseable.java:165)   @ com.typesafe.config.impl.parseable.parse(parseable.java:204)   @ com.typesafe.config.impl.configimpl$1.call(configimpl.java:368)   @ com.typesafe.config.impl.configimpl$1.call(configimpl.java:365)   @ com.typesafe.config.impl.configimpl$loadercache.getorelseupdate(configimpl.java:58)   @ com.typesafe.config.impl.configimpl.computecachedconfig(configimpl.java:86)   @ com.typesafe.config.impl.configimpl.defaultreference(configimpl.java:365)

here command running:

/usr/lib/jvm/java-7-openjdk//bin/java -xmx256m -xms32m -xbootclasspath/a:$bootcp -classpath '""' -dscala.home=/usr/opt/scala -dscala.usejavacp=true -jar /home/nick/repos/testrunnnertest/lib/scalatest.jar -r target/scala-2.10/test-classes -o

the value $bootcp massive list of dependencies including application jars, dependencies in .ivy2 , folders containing config files (/conf, /test/resources). copied command scala shell script. used value $bootcp value -classpath, still had same problem.

this problem happens when run acceptance tests spinning play framework test server. seems problem loading main application configs in /conf rather /test/resources configs appear load find when unit , integration tests happily run.

coming question pretty late, did ever figure out? typesafe config version on classpath?

line 509 on master doesn't quite right line: https://github.com/typesafehub/config/blob/master/config/src/main/java/com/typesafe/config/impl/parseable.java#l509

so may have version different source.

version 1.0.2 line 509 looks maybe more likely: https://github.com/typesafehub/config/blob/v1.0.2/config/src/main/java/com/typesafe/config/impl/parseable.java#l509

on line class loader null guess? it's supposed come here in trace: https://github.com/typesafehub/config/blob/v1.0.2/config/src/main/java/com/typesafe/config/impl/configimpl.java#l365 in turn comes from: https://github.com/typesafehub/config/blob/v1.0.2/config/src/main/java/com/typesafe/config/configfactory.java#l380

so 1 theory thread has no context class loader set in case throws exception. can't tell why that's case in scenario, if is, perhaps lead.

i don't think typesafe config should throw npe "late" in case created https://github.com/typesafehub/config/issues/155 fix up. problem in play and/or how you're setting things thread context class loader null , no other class loader provided configfactory methods.

this assuming npe null class loader, don't think that's problem, looks plausible stack trace.
