Bug Report

[Yuusuke Yoshimoto <immortal836@xxxxxxxxx>]

Hello, I'm Yusuke Yoshimoto, a Japanese university student majoring in
computer science. I found a minor bug in the standard completion function
_java_class and fixed it. The bug is that typed string gets broken if
$JAVA_TOOL_OPTIONS is set and -classpath is designated as jar files. For
example, given that $JAVA_TOOL_OPTIONS is '-Dfile.encoding=UTF-8', I type

java -classpath hamcrest-all-1.3.jar:junit-4.11.jar:

and hit tab, then the input goes to the following:

java -classpath hamcrest-all-1.3.jar:junit-4.11.jar: Picked up
JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8
Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8

To fix this, change line 18 of zsh-5.0.2/Completion/Unix/Type/_java_class
    c+=( ${${${(M)$(_call_program jar_classes jar -tf
$i)##*.class}%%.class}:gs#/#.#} )
into
    c+=( ${${${(M)$(_call_program jar_classes jar -tf $i
2>/dev/null)##*.class}%%.class}:gs#/#.#} )
Thank you.
