nullpointerexception - Jasypt fails to initialize on Android 5.1.1 and above, ClassLoader is null -


i using jasypt (compile 'org.jasypt:jasypt:1.9.2') standard pbe encryptor

    standardpbebyteencryptor strongbinaryencryptor = new standardpbebyteencryptor();     strongbinaryencryptor.setalgorithm("...");     strongbinaryencryptor.setkeyobtentioniterations(...);     strongbinaryencryptor.setprovidername(bouncycastleprovider.provider_name);     strongbinaryencryptor.setpassword("...");     byte[] encryptedbytes = strongbinaryencryptor.encrypt(bytes);

and used work without problem, crashes following root exception:

e/androidruntime:  caused by: java.lang.nullpointerexception: attempt invoke virtual method 'java.lang.class java.lang.classloader.loadclass(java.lang.string)' on null object reference e/androidruntime:     @ org.jasypt.normalization.normalizer.initializeicu4j(normalizer.java:139) e/androidruntime:     @ org.jasypt.normalization.normalizer.normalizetonfc(normalizer.java:96) e/androidruntime:     @ org.jasypt.encryption.pbe.standardpbebyteencryptor.initialize(standardpbebyteencryptor.java:661) e/androidruntime:     @ org.jasypt.encryption.pbe.standardpbebyteencryptor.encrypt(standardpbebyteencryptor.java:873) 

the same code works on kitkat phone , lollipop emulator, example crashes on oneplusone.

if @ source, see this:

static void initializeicu4j() throws classnotfoundexception {             thread.currentthread().getcontextclassloader().loadclass(icu_normalizer_class_name);     useicunormalizer = boolean.true; }

which means thread.currentthread().getcontextclassloader() null. didn't use happen, , don't know caused change in behavior. not sure should fix it.

any ideas?

based on wiki page has since been removed google code, used bug in dalvik well, patch commited in froyo. however, art seems have resurfaced exact same problem.

apparently per https://web.archive.org/web/20120303234738/http://code.google.com/p/dalvik/wiki/javaxpackages solution initialize class loader manually in activity.oncreate().

public class hellostax extends activity {   @override public void oncreate(bundle savedinstancestate) {      ...      /*      * ensure factory implementation loaded application      * classpath (which contains implementation classes), rather      * system classpath (which doesn't).      */     thread.currentthread().setcontextclassloader(getclass().getclassloader());      ...   }

Redirect to a HTTPS version using .htaccess -

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^
