Package org.perlito.Perlito5 does not exist with jrunscript #50

Closed dionys closed 6 years ago

dionys commented 6 years ago

When I try to run on last master:

jrunscript -cp .:perlito.jar -l Perl5 -e 'print 1'

I receive the following error message:

/PlEval0.java:1: error: package org.perlito.Perlito5 does not exist

script error: Unknown error during compilation.

Running make test-5jar is ok. Runing java -jar perlito5.jar -I src5/lib -e 'print 1' is ok. Only jrunscript throws the error.

fglock commented 6 years ago

Note that

jrunscript -cp .:perlito.jar -l Perl5 -e 'print 1'

should be:

jrunscript -cp .:perlito5.jar -l Perl5 -e 'print 1'

but that doesn't explain the problem, because even this works here:

jrunscript -cp . -l Perl5 -e 'print 1'

The error may be related to the problem fixed in commit 066f25cfa12bde0543615f6a23126f0093726d0a from about 2 weeks ago:

classLoader = new DynamicClassLoader( new PlArray().getClass().getClassLoader() );

This patch makes sure that eval runs in the same ClassLoader context as the Perl runtime (PlArray comes from the Perl runtime).

I can't reproduce the bug here.

Would you try the sequence below, hopefully it will give us some hints on how to reproduce the problem:

git reset --hard
git pull
make clean
make
jrunscript -cp .:perlito5.jar -l Perl5 -e 'print "1\n" '
java -version
git show --oneline -s
dionys commented 6 years ago

Yes, it's typo. I ran:

jrunscript -cp .:perlito5.jar -l Perl5 -e 'print 1'

The error is not solved after all your commands are executed.

I can reproduce with Java 8:

$ java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

The error goes away with Java 9:

$ java -version
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

73ade0c seems to fix it, tested in Oracle Java "1.8.0_131" and "9.0.1"

It works. Thanks!
